- * (Suggestion: First read the macro, then read this explanation.
- *
- * Either generate the next value to OR in to a pixel or break out of this
- * while loop
- *
- * This macro is used when we're trying to generate all 2^n combinations of
- * bits in mask. What we're doing here is counting in binary, except that
- * the bits we use to count may not be contiguous. This macro will be
- * called 2^n times, returning a different value in bits each time. Then
- * it will cause us to break out of a surrounding loop. (It will always be
- * called from within a while loop.)
- * On call: mask is the value we want to find all the combinations for
- * base has 1 bit set where the least significant bit of mask is set
- *
- * For example,if mask is 01010, base should be 0010 and we count like this:
- * 00010 (see this isn't so hard),
- * then we add base to bits and get 0100. (bits & ~mask) is (0100 & 0100) so
- * we add that to bits getting (0100 + 0100) =
- * 01000 for our next value.
- * then we add 0010 to get
- * 01010 and we're done (easy as 1, 2, 3)

+ *
+ * This macro is used when we're trying to generate all 2^n combinations of

+ * the bits we use to count may not be contiguous. This macro will be
+ * called 2^n times, returning a different value in bits each time. Then
+ * it will cause us to break out of a surrounding loop. (It will always be
+ * called from within a while loop.)
+ * On call: mask is the value we want to find all the combinations for
+ * base has 1 bit set where the least significant bit of mask is set
+ *
+ * For example,if mask is 01010, base should be 0010 and we count like this:
+ * 00010 (see this isn't so hard),
+ * then we add base to bits and get 0100. (bits & ~mask) is (0100 & 0100) so
+ * we add that to bits getting (0100 + 0100) =
+ * 01000 for our next value.
+ * then we add 0010 to get
+ * 01010 and we're done (easy as 1, 2, 3)

-/**
- * @file
- * This file describes the model for sending core enter/leave events and
- * focus in/out in the case of multiple pointers/keyboard foci.
- *
- * Since we can't send more than one Enter or Leave/Focus in or out event per
- * window to a core client without confusing it, this is a rather complicated
- * approach.
- *
- * For a full description of the enter/leave model from a window's
- * perspective, see
- * http://lists.freedesktop.org/archives/xorg/2008-August/037606.html
- *
- * For a full description of the focus in/out model from a window's
- * perspective, see
- * http://lists.freedesktop.org/archives/xorg/2008-December/041740.html
- *
- * Additional notes:
- * - The core protocol spec says that "In a LeaveNotify event, if a child of the
- * event window contains the initial position of the pointer, then the child
- * component is set to that child. Otherwise, it is None. For an EnterNotify
- * event, if a child of the event window contains the final pointer position,
- * then the child component is set to that child. Otherwise, it is None."
- *
- * By inference, this means that only NotifyVirtual or NotifyNonlinearVirtual
- * events may have a subwindow set to other than None.
- *
- * - NotifyPointer events may be sent if the focus changes from window A to
- * B. The assumption used in this model is that NotifyPointer events are only
- * sent for the pointer paired with the keyboard that is involved in the focus
- * events. For example, if F(W) changes because of keyboard 2, then
- * NotifyPointer events are only sent for pointer 2.

+ * @file
+ * This file describes the model for sending core enter/leave events and
+ * focus in/out in the case of multiple pointers/keyboard foci.
+ *
+ * Since we can't send more than one Enter or Leave/Focus in or out event per
+ * window to a core client without confusing it, this is a rather complicated
+ * approach.
+ *
+ * For a full description of the enter/leave model from a window's
+ * perspective, see
+ * http://lists.freedesktop.org/archives/xorg/2008-August/037606.html
+ *
+ * For a full description of the focus in/out model from a window's
+ * perspective, see
+ * http://lists.freedesktop.org/archives/xorg/2008-December/041740.html
+ *
+ * Additional notes:
+ * - The core protocol spec says that "In a LeaveNotify event, if a child of the
+ * event window contains the initial position of the pointer, then the child
+ * component is set to that child. Otherwise, it is None. For an EnterNotify
+ * event, if a child of the event window contains the final pointer position,
+ * then the child component is set to that child. Otherwise, it is None."
+ *
+ * By inference, this means that only NotifyVirtual or NotifyNonlinearVirtual
+ * events may have a subwindow set to other than None.
+ *
+ * - NotifyPointer events may be sent if the focus changes from window A to
+ * B. The assumption used in this model is that NotifyPointer events are only
+ * sent for the pointer paired with the keyboard that is involved in the focus
+ * events. For example, if F(W) changes because of keyboard 2, then
+ * NotifyPointer events are only sent for pointer 2.

+ * 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 RegionValidate in order to support several speed improvements
+ * to miValidateTree. Bob Scheifler changed the representation to be more
+ * compact when empty or a single rectangle, and did a bunch of gratuitous
+ * reformatting.
