- * 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 miRegionValidate 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.
