-REMOVE THIS FILE BEFORE MERGING WITH TRUNK
-------------------------------------------
-
-OUTSTANDING BUGS
-
-demos/reflect - reading back Z on Voodoo3, image offset to right
- Fixed in latest Glide.
-
-Q3 - some polygons drawn as vertical strips, similar to bug that was
- seen in demos/fire. Voodoo3 only. May be related to glDepthMask
- or glColorMask.
-
-book/fog - not fogging
- Fog in orthograph mode still not implemented. Checking with
- 3dfx engineers for ideas.
-
-Q3 demo crashes after changing display settings
- but the full Q3 game version seems OK.
-
-
-
-MORE OUTSTANDING BUGS
-
-private context was NULL! causing immediate failure of any glx prog. cant
-reproduce after restarting the X server. putting it down as halluc.
-
-texture object image was NULL, causing segmentation failure. happens with
-prboom. ive put a check in tdfx_texstate.c but this isn't a fix.
-
-prboom, wall textures near first chainsaw aren't bound properly. sideways
-movements causes the wall textures to move with you. prboom busted?
-
-16bpp mode, quake3, windowed, q3dm1, floor under rocketlauncher bands. it
-looks like multitexturing gone wrong. i'll disable a tmu and test.
-
-sof, polygons appear at wrong x,y,z positions, intermittent, have not yet
-found reliable way of reproducing. culling? sometimes polys disappear.
-
-descent3 is all black in 16bpp mode - FIXED (palette problems)
-
-smeared pixels in quake3 - FIXED (texture memory overlapped FB)
-
-
-

- * Because the Linear Frame Buffer is not necessarily aligned
- * with the depth buffer, we have to do some fiddling
- * around to get the right addresses.
- *
- * Perhaps a picture is in order. The Linear Frame Buffer
- * looks like this:
- *
- * |<----------------------info.strideInBytes------------->|
- * |<-----physicalStrideInBytes------->|
- * +-----------------------------------+xxxxxxxxxxxxxxxxxxx+
- * | | |
- * | Legal Memory | Forbidden Zone |
- * | | |
- * +-----------------------------------+xxxxxxxxxxxxxxxxxxx+
- *
- * You can only reliably read and write legal locations. Reads
- * and writes from the Forbidden Zone will return undefined values,
- * and may cause segmentation faults.
- *
- * Now, the depth buffer may not end up in a location such each
- * scan line is an LFB line. For example, the depth buffer may
- * look like this:
- *
- * wrapped ordinary.
- * +-----------------------------------+xxxxxxxxxxxxxxxxxxx+
- * |0000000000000000000000 | | back
- * |1111111111111111111111 | | buffer
- * |2222222222222222222222 | |
- * |4096b align. padxx00000000000000000| Forbidden Zone | depth
- * |0000 11111111111111111| | buffer
- * |1111 22222222222222222| |
- * |2222 | |
- * +-----------------------------------+xxxxxxxxxxxxxxxxxxx+
- * where each number is the scan line number. We know it will
- * be aligned on 128 byte boundaries, at least. Aligning this
- * on a scanline boundary causes the back and depth buffers to
- * thrash in the SST1 cache. (Note that the back buffer is always
- * allocated at the beginning of LFB memory, and so it is always
- * properly aligned with the LFB stride.)
- *
- * We call the beginning of the line (which is the rightmost
- * part of the depth line in the picture above) the *ordinary* part
- * of the scanline, and the end of the line (which is the
- * leftmost part, one line below) the *wrapped* part of the scanline.
- * a.) We need to know what x value to subtract from the screen
- * x coordinate to index into the wrapped part.
- * b.) We also need to figure out if we need to read from the ordinary
- * part scan line, or from the wrapped part of the scan line.
- *
- * [ad a]
- * The first wrapped x coordinate is that coordinate such that
- * depthBufferOffset&(info.strideInBytes) + x*elmentSize {*}
- * > physicalStrideInBytes
- * where depthBufferOffset is the LFB distance in bytes
- * from the back buffer to the depth buffer. The expression
- * depthBufferOffset&(info.strideInBytes)
- * is then the offset (in bytes) from the beginining of (any)
- * depth buffer line to first element in the line.
- * Simplifying inequation {*} above we see that x is the smallest
- * value such that
- * x*elementSize > physicalStrideInBytes {**}
- * - depthBufferOffset&(info.strideInBytes)
- * Now, we know that both the summands on the right are multiples of
- * 128, and elementSize <= 4, so if equality holds in {**}, x would
- * be a multiple of 32. Thus we can set x to
- * xwrapped = (physicalStrideInBytes
- * - depthBufferOffset&(info.strideInBytes))/elementSize
- * + 1
- *
- * [ad b]
- * Question b is now simple. We read from the wrapped scan line if
- * x is greater than xwrapped.
