+====================
+
+The pixman coding style is close to cairo's with one exception: braces
+go on their own line, rather than on the line of the if/while/for:
+
+ if (condition)
+ {
+ do_something();
+ do_something_else();
+ }
+
+not
+
+ if (condition) {
+ do_something();
+ do_something_else();
+ }
+
+
+
+Indentation
+===========
+
+Each new level is indented four spaces:
+
+ if (condition)
+ do_something();
+
+This may be achieved with space characters or with a combination of
+tab characters and space characters. Tab characters are interpreted as
+
+ Advance to the next column which is a multiple of 8.
+
+
+Names
+=====
+
+In all names, words are separated with underscores. Do not use
+CamelCase for any names.
+
+Macros have ALL_CAPITAL_NAMES
+
+Type names are in lower case and end with "_t". For example
+pixman_image_t.
+
+Labels, functions and variables have lower case names.
+
+
+Braces
+======
+
+Braces always go on their own line:
+
+ if (condition)
+ {
+ do_this ();
+ do_that ();
+ }
+ else
+ {
+ do_the_other ();
+ }
+
+Rules for braces and substatements of if/while/for/do:
+
+* If a substatement spans multiple lines, then there must be braces
+ around it.
+
+* If the condition of an if/while/for spans multiple lines, then
+ braces must be used for the substatements.
+
+* If one substatement of an if statement has braces, then the other
+ must too.
+
+* Otherwise, don't add braces.
+
+
+Comments
+========
+
+For comments either like this:
+
+ /* One line comment */
+
+or like this:
+
+ /* This is a multi-line comment
+ *
+ * It extends over multiple lines
+ */
+
+Generally comments should say things that aren't clear from the code
+itself. If too many comments say obvious things, then people will just
+stop reading all comments, including the good ones.
+
+
+Whitespace
+==========
+
+* Put a single space after commas
+
+* Put spaces around arithmetic operators such a +, -, *, /:
+
+ y * stride + x
+
+ x / unit_x
+
+* Do not put spaces after the address-of operator, the * when used as
+ a pointer derefernce or the ! and ~ operators:
+
+ &foo;
+
+ ~0x00000000
+
+ !condition
+
+ *result = 100
+
+* Break up long lines (> ~80 characters) and use whitespace to align
+ things nicely. This is one way:
+
+ some_very_long_function name (
+ implementation, op, src, mask, dest,
+ src_x, src_y, mask_x, mask_y, dest_x, dest_y,
+ width, height);
+
+ This is another:
+
+ some_very_long_function_name (implementation, op,
+ src, mask, dest,
+ src_x, src_y,
+ mask_x, mask_y,
+ dest_x, dest_y,
+ width, height);
+
+* Separate logically distinct chunks with a single newline. This
+ obviously applies between functions, but also applies within a
+ function or block or structure definition.
+
+* Use a newline after a block of variable declarations.
+
+* Use a single space before a left parenthesis, except where the
+ standard will not allow it, (eg. when defining a parameterized macro).
+
+* Don't eliminate newlines just because things would still fit on one
+ line. This breaks the expected visual structure of the code making
+ it much harder to read and understand:
+
+ if (condition) foo (); else bar (); /* Yuck! */
+
+
+Function Definitions
+====================
+
+Function definitions should take the following form:
+
+ void
+ my_function (int argument)
+ {
+ do_my_things ();
+ }
+
+If all the parameters to a function fit naturally on one line, format
+them that way. Otherwise, put one argument on each line, adding
+whitespace so that the parameter names are aligned with each other.
+
+I.e., do either this:
+
+ void
+ short_arguments (const char *str, int x, int y, int z)
+ {
+ }
+
+or this:
+
+ void
+ long_arguments (const char *char_star_arg,
+ int int_arg,
+ double *double_star_arg,
+ double double_arg)
+ {
+ }
+
+
+Mode lines
+==========
+
+Given the rules above, what is the best way to simplify one's life as
+a code monkey? Get your editor to do most of the tedious work of
+beautifying your code!
+
+As a reward for reading this far, here are some mode lines for the more
+popular editors:
+/*
+ * vim:sw=4:sts=4:ts=8:tw=78:fo=tcroq:cindent:cino=\:0,(0
+ * vim:isk=a-z,A-Z,48-57,_,.,-,>

+
+1) Ensure that there are no uncommitted changes or unpushed commits,
+ and that you are up to date with the latest commits in the central
+ repository. Here are a couple of useful commands:
+
+ git diff (no output)
+
+ git status (should report "nothing to commit")
+
+ git log master...origin (no output; note: *3* dots)
+
+2) Increment pixman_(major|minor|micro) in configure.ac according to
+ the directions in that file. Use git commit to record this.
+
+3) Make sure that new version works, including
+
+ - make distcheck passes
+
+ - the X server still works with the new pixman version
+ installed
+
+ - the cairo test suite hasn't gained any new failures compared
+ to last pixman version.
+
+4) Use "git commit" to record any changes made in step 3.
+
+5) Generate and publish the tar files by running
+
+ make PREV=<last version> GPGKEY=<your gpg key id> release-publish
+
+ If your freedesktop user name is different from your local one,
+ then also set the variable USER to your freedesktop user name.
+
+6) Run
+
+ make release-publish-message
+
+ to generate a draft release announcement. Edit it as appropriate and
+ send it to
+
+ cairo-announce@cairographics.org
+
+ pixman@lists.freedesktop.org
+
+ xorg-announce@lists.freedesktop.org
+
+7) Increment pixman_micro to the next larger (odd) number in
+ configure.ac. Commit this change, and push all commits created
+ during this process using
+
+ git push
+ git push --tags
+
+ You must use "--tags" here; otherwise the new tag will not
+ be pushed out.
+

+ * In the radial gradient problem we are given two circles (c₁,r₁) and
+ * (c₂,r₂) that define the gradient itself. Then, for any point p, we
+ * must compute the value(s) of t within [0.0, 1.0] representing the
+ * circle(s) that would color the point.
+ *
+ * There are potentially two values of t since the point p can be
+ * colored by both sides of the circle, (which happens whenever one
+ * circle is not entirely contained within the other).
+ *
+ * If we solve for a value of t that is outside of [0.0, 1.0] then we
+ * use the extend mode (NONE, REPEAT, REFLECT, or PAD) to map to a
+ * value within [0.0, 1.0].
+ *
+ * Here is an illustration of the problem:
+ *
+ * p₂
+ * p •
+ * • ╲
+ * · ╲r₂
+ * p₁ · ╲
+ * • θ╲
+ * ╲ ╌╌•
+ * ╲r₁ · c₂
+ * θ╲ ·
+ * ╌╌•
+ * c₁
+ *
+ * Given (c₁,r₁), (c₂,r₂) and p, we must find an angle θ such that two
+ * points p₁ and p₂ on the two circles are collinear with p. Then, the
+ * desired value of t is the ratio of the length of p₁p to the length
+ * of p₁p₂.
+ *
+ * So, we have six unknown values: (p₁x, p₁y), (p₂x, p₂y), θ and t.
+ * We can also write six equations that constrain the problem:
+ *
+ * Point p₁ is a distance r₁ from c₁ at an angle of θ:
+ *
+ * 1. p₁x = c₁x + r₁·cos θ
+ * 2. p₁y = c₁y + r₁·sin θ
+ *
+ * Point p₂ is a distance r₂ from c₂ at an angle of θ:
+ *
+ * 3. p₂x = c₂x + r2·cos θ
+ * 4. p₂y = c₂y + r2·sin θ
+ *
+ * Point p lies at a fraction t along the line segment p₁p₂:
+ *
+ * 5. px = t·p₂x + (1-t)·p₁x
+ * 6. py = t·p₂y + (1-t)·p₁y
+ *
+ * To solve, first subtitute 1-4 into 5 and 6:
+ *
+ * px = t·(c₂x + r₂·cos θ) + (1-t)·(c₁x + r₁·cos θ)
+ * py = t·(c₂y + r₂·sin θ) + (1-t)·(c₁y + r₁·sin θ)
+ *
+ * Then solve each for cos θ and sin θ expressed as a function of t:
+ *
+ * cos θ = (-(c₂x - c₁x)·t + (px - c₁x)) / ((r₂-r₁)·t + r₁)
+ * sin θ = (-(c₂y - c₁y)·t + (py - c₁y)) / ((r₂-r₁)·t + r₁)
+ *
+ * To simplify this a bit, we define new variables for several of the
+ * common terms as shown below:
+ *
+ * p₂
+ * p •
+ * • ╲
+ * · ┆ ╲r₂
+ * p₁ · ┆ ╲
+ * • pdy┆ ╲
+ * ╲ ┆ •c₂
+ * ╲r₁ ┆ · ┆
+ * ╲ ·┆ ┆cdy
+ * •╌╌╌╌┴╌╌╌╌╌╌╌┘
+ * c₁ pdx cdx
+ *
+ * cdx = (c₂x - c₁x)
+ * cdy = (c₂y - c₁y)
+ * dr = r₂-r₁
+ * pdx = px - c₁x
+ * pdy = py - c₁y
+ *
+ * Note that cdx, cdy, and dr do not depend on point p at all, so can
+ * be pre-computed for the entire gradient. The simplifed equations
+ * are now:
+ *
+ * cos θ = (-cdx·t + pdx) / (dr·t + r₁)
+ * sin θ = (-cdy·t + pdy) / (dr·t + r₁)
+ *
+ * Finally, to get a single function of t and eliminate the last
+ * unknown θ, we use the identity sin²θ + cos²θ = 1. First, square
+ * each equation, (we knew a quadratic was coming since it must be
+ * possible to obtain two solutions in some cases):
+ *
+ * cos²θ = (cdx²t² - 2·cdx·pdx·t + pdx²) / (dr²·t² + 2·r₁·dr·t + r₁²)
+ * sin²θ = (cdy²t² - 2·cdy·pdy·t + pdy²) / (dr²·t² + 2·r₁·dr·t + r₁²)
+ *
+ * Then add both together, set the result equal to 1, and express as a
+ * standard quadratic equation in t of the form At² + Bt + C = 0
+ *
+ * (cdx² + cdy² - dr²)·t² - 2·(cdx·pdx + cdy·pdy + r₁·dr)·t + (pdx² + pdy² - r₁²) = 0
+ *
+ * In other words:
+ *
+ * A = cdx² + cdy² - dr²
+ * B = -2·(pdx·cdx + pdy·cdy + r₁·dr)
+ * C = pdx² + pdy² - r₁²
+ *
+ * And again, notice that A does not depend on p, so can be
+ * precomputed. From here we just use the quadratic formula to solve
+ * for t:
+ *
+ * t = (-2·B ± ⎷(B² - 4·A·C)) / 2·A

A Region is simply a set of disjoint - * (non-overlapping) rectangles, plus an "extent" rectangle which is the - * smallest single rectangle that contains all the non-overlapping rectangles. - * - * A Region is implemented as a "y-x-banded" array of rectangles. This array - * imposes two degrees of order. First, all rectangles are sorted by top side - * y coordinate first (y1), and then by left side x coordinate (x1). - * - * Furthermore, the rectangles are grouped into "bands". Each rectangle in a - * band has the same top y coordinate (y1), and each has the same bottom y - * coordinate (y2). Thus all rectangles in a band differ only in their left - * and right side (x1 and x2). Bands are implicit in the array of rectangles: - * there is no separate list of band start pointers. - * - * The y-x band representation does not minimize rectangles. In particular, - * if a rectangle vertically crosses a band (the rectangle has scanlines in - * the y1 to y2 area spanned by the band), then the rectangle may be broken - * down into two or more smaller rectangles stacked one atop the other. - * - * ----------- ----------- - * | | | | band 0 - * | | -------- ----------- -------- - * | | | | in y-x banded | | | | band 1 - * | | | | form is | | | | - * ----------- | | ----------- -------- - * | | | | band 2 - * -------- -------- - * - * An added constraint on the rectangles is that they must cover as much - * horizontal area as possible: no two rectangles within a band are allowed - * to touch. - * - * Whenever possible, bands will be merged together to cover a greater vertical - * distance (and thus reduce the number of rectangles). Two bands can be merged - * only if the bottom of one touches the top of the other and they have - * rectangles in the same places (of the same width, of course). - * - * Adam de Boor wrote most of the original region code. Joel McCormack - * substantially modified or rewrote most of the core arithmetic routines, and - * added pixman_region_validate in order to support several speed improvements - * to pixman_region_validate_tree. Bob Scheifler changed the representation - * to be more compact when empty or a single rectangle, and did a bunch of - * gratuitous reformatting. Carl Worth did further gratuitous reformatting - * while re-merging the server and client region code into libpixregion. - * Soren Sandmann did even more gratuitous reformatting. - */ - -/* true iff two Boxes overlap */ -#define EXTENTCHECK(r1, r2) \ - (!( ((r1)->x2 <= (r2)->x1) || \ - ((r1)->x1 >= (r2)->x2) || \ - ((r1)->y2 <= (r2)->y1) || \ - ((r1)->y1 >= (r2)->y2) ) ) - -/* true iff (x,y) is in Box */ -#define INBOX(r, x, y) \ - ( ((r)->x2 > x) && \ - ((r)->x1 <= x) && \ - ((r)->y2 > y) && \ - ((r)->y1 <= y) ) - -/* true iff Box r1 contains Box r2 */ -#define SUBSUMES(r1, r2) \ - ( ((r1)->x1 <= (r2)->x1) && \ - ((r1)->x2 >= (r2)->x2) && \ - ((r1)->y1 <= (r2)->y1) && \ - ((r1)->y2 >= (r2)->y2) ) - -static size_t -PIXREGION_SZOF (size_t n) -{ - size_t size = n * sizeof(box_type_t);

+ * The functions in this file implement the Region abstraction used extensively
+ * throughout the X11 sample server. A Region is simply a set of disjoint
+ * (non-overlapping) rectangles, plus an "extent" rectangle which is the
+ * smallest single rectangle that contains all the non-overlapping rectangles.
+ *
+ * A Region is implemented as a "y-x-banded" array of rectangles. This array
+ * imposes two degrees of order. First, all rectangles are sorted by top side
+ * y coordinate first (y1), and then by left side x coordinate (x1).
+ *
+ * Furthermore, the rectangles are grouped into "bands". Each rectangle in a
+ * band has the same top y coordinate (y1), and each has the same bottom y
+ * coordinate (y2). Thus all rectangles in a band differ only in their left
+ * and right side (x1 and x2). Bands are implicit in the array of rectangles:
+ * there is no separate list of band start pointers.
+ *
+ * The y-x band representation does not minimize rectangles. In particular,
+ * if a rectangle vertically crosses a band (the rectangle has scanlines in
+ * the y1 to y2 area spanned by the band), then the rectangle may be broken
+ * down into two or more smaller rectangles stacked one atop the other.
+ *
+ * ----------- -----------
+ * | | | | band 0
+ * | | -------- ----------- --------
+ * | | | | in y-x banded | | | | band 1
+ * | | | | form is | | | |
+ * ----------- | | ----------- --------
+ * | | | | band 2
+ * -------- --------
+ *
+ * An added constraint on the rectangles is that they must cover as much
+ * horizontal area as possible: no two rectangles within a band are allowed
+ * to touch.
+ *
+ * Whenever possible, bands will be merged together to cover a greater vertical
+ * distance (and thus reduce the number of rectangles). Two bands can be merged
+ * only if the bottom of one touches the top of the other and they have
+ * rectangles in the same places (of the same width, of course).
+ *
+ * Adam de Boor wrote most of the original region code. Joel McCormack
+ * substantially modified or rewrote most of the core arithmetic routines, and
+ * added pixman_region_validate in order to support several speed improvements
+ * to pixman_region_validate_tree. Bob Scheifler changed the representation
+ * to be more compact when empty or a single rectangle, and did a bunch of
+ * gratuitous reformatting. Carl Worth did further gratuitous reformatting
+ * while re-merging the server and client region code into libpixregion.
+ * Soren Sandmann did even more gratuitous reformatting.

+ * into horizontal bands where points are covered only by one region
+ * or by both. For the first case, the non_overlap_func is called with
+ * each the band and the band's upper and lower extents. For the
+ * second, the overlap_func is called to process the entire band. It
+ * is responsible for clipping the rectangles in the band, though
+ * this function provides the boundaries.
+ * At the end of each band, the new region is coalesced, if possible,
+ * to reduce the number of rectangles in the region.

+
+Images will eventually have these virtual functions:
+
+ get_scanline()
+ get_scanline_wide()
+ get_pixel()
+ get_pixel_wide()
+ get_untransformed_pixel()
+ get_untransformed_pixel_wide()
+ get_unfiltered_pixel()
+ get_unfiltered_pixel_wide()
+
+ store_scanline()
+ store_scanline_wide()
+
+1.
+
+Initially we will just have get_scanline() and get_scanline_wide();
+these will be based on the ones in pixman-compose. Hopefully this will
+reduce the complexity in pixman_composite_rect_general().
+
+Note that there is access considerations - the compose function is
+being compiled twice.
+
+
+2.
+
+Split image types into their own source files. Export noop virtual
+reinit() call. Call this whenever a property of the image changes.
+
+
+3.
+
+Split the get_scanline() call into smaller functions that are
+initialized by the reinit() call.
+
+The Render Algorithm:
+ (first repeat, then filter, then transform, then clip)
+
+Starting from a destination pixel (x, y), do
+
+ 1 x = x - xDst + xSrc
+ y = y - yDst + ySrc
+
+ 2 reject pixel that is outside the clip
+
+ This treats clipping as something that happens after
+ transformation, which I think is correct for client clips. For
+ hierarchy clips it is wrong, but who really cares? Without
+ GraphicsExposes hierarchy clips are basically irrelevant. Yes,
+ you could imagine cases where the pixels of a subwindow of a
+ redirected, transformed window should be treated as
+ transparent. I don't really care
+
+ Basically, I think the render spec should say that pixels that
+ are unavailable due to the hierarcy have undefined content,
+ and that GraphicsExposes are not generated. Ie., basically
+ that using non-redirected windows as sources is fail. This is
+ at least consistent with the current implementation and we can
+ update the spec later if someone makes it work.
+
+ The implication for render is that it should stop passing the
+ hierarchy clip to pixman. In pixman, if a souce image has a
+ clip it should be used in computing the composite region and
+ nowhere else, regardless of what "has_client_clip" says. The
+ default should be for there to not be any clip.
+
+ I would really like to get rid of the client clip as well for
+ source images, but unfortunately there is at least one
+ application in the wild that uses them.
+
+ 3 Transform pixel: (x, y) = T(x, y)
+
+ 4 Call p = GetUntransformedPixel (x, y)
+
+ 5 If the image has an alpha map, then
+
+ Call GetUntransformedPixel (x, y) on the alpha map
+
+ add resulting alpha channel to p
+
+ return p
+
+ Where GetUnTransformedPixel is:
+
+ 6 switch (filter)
+ {
+ case NEAREST:
+ return GetUnfilteredPixel (x, y);
+ break;
+
+ case BILINEAR:
+ return GetUnfilteredPixel (...) // 4 times
+ break;
+
+ case CONVOLUTION:
+ return GetUnfilteredPixel (...) // as many times as necessary.
+ break;
+ }
+
+ Where GetUnfilteredPixel (x, y) is
+
+ 7 switch (repeat)
+ {
+ case REPEAT_NORMAL:
+ case REPEAT_PAD:
+ case REPEAT_REFLECT:
+ // adjust x, y as appropriate
+ break;
+
+ case REPEAT_NONE:
+ if (x, y) is outside image bounds
+ return 0;
+ break;
+ }
+
+ return GetRawPixel(x, y)
+
+ Where GetRawPixel (x, y) is
+
+ 8 Compute the pixel in question, depending on image type.
+
+For gradients, repeat has a totally different meaning, so
+UnfilteredPixel() and RawPixel() must be the same function so that
+gradients can do their own repeat algorithm.
+
+So, the GetRawPixel
+
+ for bits must deal with repeats
+ for gradients must deal with repeats (differently)
+ for solids, should ignore repeats.
+
+ for polygons, when we add them, either ignore repeats or do
+ something similar to bits (in which case, we may want an extra
+ layer of indirection to modify the coordinates).
+
+It is then possible to build things like "get scanline" or "get tile" on
+top of this. In the simplest case, just repeatedly calling GetPixel()
+would work, but specialized get_scanline()s or get_tile()s could be
+plugged in for common cases.
+
+By not plugging anything in for images with access functions, we only
+have to compile the pixel functions twice, not the scanline functions.
+
+And we can get rid of fetchers for the bizarre formats that no one
+uses. Such as b2g3r3 etc. r1g2b1? Seriously? It is also worth
+considering a generic format based pixel fetcher for these edge cases.
+
+Since the actual routines depend on the image attributes, the images
+must be notified when those change and update their function pointers
+appropriately. So there should probably be a virtual function called
+(* reinit) or something like that.
+
+There will also be wide fetchers for both pixels and lines. The line
+fetcher will just call the wide pixel fetcher. The wide pixel fetcher
+will just call expand, except for 10 bit formats.
+
+Rendering pipeline:
+
+Drawable:
+ 0. if (picture has alpha map)
+ 0.1. Position alpha map according to the alpha_x/alpha_y
+ 0.2. Where the two drawables intersect, the alpha channel
+ Replace the alpha channel of source with the one
+ from the alpha map. Replacement only takes place
+ in the intersection of the two drawables' geometries.
+ 1. Repeat the drawable according to the repeat attribute
+ 2. Reconstruct a continuous image according to the filter
+ 3. Transform according to the transform attribute
+ 4. Position image such that src_x, src_y is over dst_x, dst_y
+ 5. Sample once per destination pixel
+ 6. Clip. If a pixel is not within the source clip, then no
+ compositing takes place at that pixel. (Ie., it's *not*
+ treated as 0).
+
+ Sampling a drawable:
+
+ - If the channel does not have an alpha channel, the pixels in it
+ are treated as opaque.
+
+ Note on reconstruction:
+
+ - The top left pixel has coordinates (0.5, 0.5) and pixels are
+ spaced 1 apart.
+
+Gradient:
+ 1. Unless gradient type is conical, repeat the underlying (0, 1)
+ gradient according to the repeat attribute
+ 2. Integrate the gradient across the plane according to type.
+ 3. Transform according to transform attribute
+ 4. Position gradient
+ 5. Sample once per destination pixel.
+ 6. Clip
+
+Solid Fill:
+ 1. Repeat has no effect
+ 2. Image is already continuous and defined for the entire plane
+ 3. Transform has no effect
+ 4. Positioning has no effect
+ 5. Sample once per destination pixel.
+ 6. Clip
+
+Polygon:
+ 1. Repeat has no effect
+ 2. Image is already continuous and defined on the whole plane
+ 3. Transform according to transform attribute
+ 4. Position image
+ 5. Supersample 15x17 per destination pixel.
+ 6. Clip
+
+Possibly interesting additions:
+ - More general transformations, such as warping, or general
+ shading.
+
+ - Shader image where a function is called to generate the
+ pixel (ie., uploading assembly code).
+
+ - Resampling kernels
+
+ In principle the polygon image uses a 15x17 box filter for
+ resampling. If we allow general resampling filters, then we
+ get all the various antialiasing types for free.
+
+ Bilinear downsampling looks terrible and could be much
+ improved by a resampling filter. NEAREST reconstruction
+ combined with a box resampling filter is what GdkPixbuf
+ does, I believe.
+
+ Useful for high frequency gradients as well.
+
+ (Note that the difference between a reconstruction and a
+ resampling filter is mainly where in the pipeline they
+ occur. High quality resampling should use a correctly
+ oriented kernel so it should happen after transformation.
+
+ An implementation can transform the resampling kernel and
+ convolve it with the reconstruction if it so desires, but it
+ will need to deal with the fact that the resampling kernel
+ will not necessarily be pixel aligned.
+
+ "Output kernels"
+
+ One could imagine doing the resampling after compositing,
+ ie., for each destination pixel sample each source image 16
+ times, then composite those subpixels individually, then
+ finally apply a kernel.
+
+ However, this is effectively the same as full screen
+ antialiasing, which is a simpler way to think about it. So
+ resampling kernels may make sense for individual images, but
+ not as a post-compositing step.
+
+ Fullscreen AA is inefficient without chained compositing
+ though. Consider an (image scaled up to oversample size IN
+ some polygon) scaled down to screen size. With the current
+ implementation, there will be a huge temporary. With chained
+ compositing, the whole thing ends up being equivalent to the
+ output kernel from above.
+
+ - Color space conversion
+
+ The complete model here is that each surface has a color
+ space associated with it and that the compositing operation
+ also has one associated with it. Note also that gradients
+ should have associcated colorspaces.
+
+ - Dithering
+
+ If people dither something that is already dithered, it will
+ look terrible, but don't do that, then. (Dithering happens
+ after resampling if at all - what is the relationship
+ with color spaces? Presumably dithering should happen in linear
+ intensity space).
+
+ - Floating point surfaces, 16, 32 and possibly 64 bit per
+ channel.
+
+ Maybe crack:
+
+ - Glyph polygons
+
+ If glyphs could be given as polygons, they could be
+ positioned and rasterized more accurately. The glyph
+ structure would need subpixel positioning though.
+
+ - Luminance vs. coverage for the alpha channel
+
+ Whether the alpha channel should be interpreted as luminance
+ modulation or as coverage (intensity modulation). This is a
+ bit of a departure from the rendering model though. It could
+ also be considered whether it should be possible to have
+ both channels in the same drawable.
+
+ - Alternative for component alpha
+
+ - Set component-alpha on the output image.
+
+ - This means each of the components are sampled
+ independently and composited in the corresponding
+ channel only.
+
+ - Have 3 x oversampled mask
+
+ - Scale it down by 3 horizontally, with [ 1/3, 1/3, 1/3 ]
+ resampling filter.
+
+ Is this equivalent to just using a component alpha mask?
+
+ Incompatible changes:
+
+ - Gradients could be specified with premultiplied colors. (You
+ can use a mask to get things like gradients from solid red to
+ transparent red.
+
+Refactoring pixman
+
+The pixman code is not particularly nice to put it mildly. Among the
+issues are
+
+- inconsistent naming style (fb vs Fb, camelCase vs
+ underscore_naming). Sometimes there is even inconsistency *within*
+ one name.
+
+ fetchProc32 ACCESS(pixman_fetchProcForPicture32)
+
+ may be one of the uglies names ever created.
+
+ coding style:
+ use the one from cairo except that pixman uses this brace style:

+ while (...);
+
+- PIXMAN_COMPOSITE_RECT_GENERAL() is horribly complex
+
+- switch case logic in pixman-access.c
+
+ Instead it would be better to just store function pointers in the
+ image objects themselves,
+
+ get_pixel()
+ get_scanline()
+
+- Much of the scanline fetching code is for formats that no one
+ ever uses. a2r2g2b2 anyone?
+
+ It would probably be worthwhile having a generic fetcher for any
+ pixman format whatsoever.
+
+- Code related to particular image types should be split into individual
+ files.
+
+ pixman-bits-image.c
+ pixman-linear-gradient-image.c
+ pixman-radial-gradient-image.c
+ pixman-solid-image.c
+
+- Fast path code should be split into files based on architecture:
+
+ pixman-mmx-fastpath.c
+ pixman-sse2-fastpath.c
+ pixman-c-fastpath.c
+
+ etc.
+
+ Each of these files should then export a fastpath table, which would
+ be declared in pixman-private.h. This should allow us to get rid
+ of the pixman-mmx.h files.
+
+ The fast path table should describe each fast path. Ie there should
+ be bitfields indicating what things the fast path can handle, rather than
+ like now where it is only allowed to take one format per src/mask/dest. Ie.,
+
+ {
+ FAST_a8r8g8b8 | FAST_x8r8g8b8,
+ FAST_null,
+ FAST_x8r8g8b8,
+ FAST_repeat_normal | FAST_repeat_none,
+ the_fast_path
+ }
+
+There should then be *one* file that implements pixman_image_composite().
+This should do this:
+
+ optimize_operator();
+
+ convert 1x1 repeat to solid (actually this should be done at
+ image creation time).
+
+ is there a useful fastpath?
+
+There should be a file called pixman-cpu.c that contains all the
+architecture specific stuff to detect what CPU features we have.
+
+Issues that must be kept in mind:
+
+ - we need accessor code to be preserved
+
+ - maybe there should be a "store_scanline" too?
+
+ Is this sufficient?
+
+ We should preserve the optimization where the
+ compositing happens directly in the destination
+ whenever possible.
+
+ - It should be possible to create GPU samplers from the
+ images.
+
+The "horizontal" classification should be a bit in the image, the
+"vertical" classification should just happen inside the gradient
+file. Note though that
+
+ (a) these will change if the tranformation/repeat changes.
+
+ (b) at the moment the optimization for linear gradients
+ takes the source rectangle into account. Presumably
+ this is to also optimize the case where the gradient
+ is close enough to horizontal?
+
+Who is responsible for repeats? In principle it should be the scanline
+fetch. Right now NORMAL repeats are handled by walk_composite_region()
+while other repeats are handled by the scanline code.
+
+
+(Random note on filtering: do you filter before or after
+transformation? Hardware is going to filter after transformation;
+this is also what pixman does currently). It's not completely clear
+what filtering *after* transformation means. One thing that might look
+good would be to do *supersampling*, ie., compute multiple subpixels
+per destination pixel, then average them together.

+ * A function, which can be used as a core part of the test programs,
+ * intended to detect various problems with the help of fuzzing input
+ * to pixman API (according to some templates, aka "smart" fuzzing).
+ * Some general information about such testing can be found here:
+ * http://en.wikipedia.org/wiki/Fuzz_testing
+ *
+ * It may help detecting:
+ * - crashes on bad handling of valid or reasonably invalid input to
+ * pixman API.
+ * - deviations from the behavior of older pixman releases.
+ * - deviations from the behavior of the same pixman release, but
+ * configured in a different way (for example with SIMD optimizations
+ * disabled), or running on a different OS or hardware.
+ *
+ * The test is performed by calling a callback function a huge number
+ * of times. The callback function is expected to run some snippet of
+ * pixman code with pseudorandom variations to the data feeded to
+ * pixman API. A result of running each callback function should be
+ * some deterministic value which depends on test number (test number
+ * can be used as a seed for PRNG). When 'verbose' argument is nonzero,
+ * callback function is expected to print to stdout some information
+ * about what it does.
+ *
+ * Return values from many small tests are accumulated together and
+ * used as final checksum, which can be compared to some expected
+ * value. Running the tests not individually, but in a batch helps
+ * to reduce process start overhead and also allows to parallelize
+ * testing and utilize multiple CPU cores.
+ *
+ * The resulting executable can be run without any arguments. In
+ * this case it runs a batch of tests starting from 1 and up to
+ * 'default_number_of_iterations'. The resulting checksum is
+ * compared with 'expected_checksum' and FAIL or PASS verdict
+ * depends on the result of this comparison.
+ *
+ * If the executable is run with 2 numbers provided as command line
+ * arguments, they specify the starting and ending numbers for a test
+ * batch.
+ *
+ * If the executable is run with only one number provided as a command
+ * line argument, then this number is used to call the callback function
+ * once, and also with verbose flag set.
