+ * bitmask.c 1.0
+ * -------------
+ * Simple and efficient bitmask collision detection routines
+ * Copyright (C) 2002 Ulf Ekstrom except for the bitcount function.
+ *
+ * A bitmask is a simple array of bits, which can be used for
+ * 2d collision detection. Set 'unoccupied' area to zero and
+ * occupies areas to one and use the bitmask_overlap*() functions
+ * to check for collisions.
+ * The current implementation uses 32 bit wide stripes to hold
+ * the masks, but should work just as well with 64 bit sizes.
+ * (Note that the current bitcount function is 32 bit only!)
+ *
+ * The overlap tests uses the following offsets (which may be negative):
+ *
+ * +----+----------..
+ * |A | yoffset
+ * | +-+----------..
+ * +--|B
+ * |xoffset
+ * | |
+ * : :
+ *
+ * For optimal collision detection performance combine these functions
+ * with some kind of pre-sorting to avoid comparing objects far from
+ * each other.
+ *
+ * BUGS: No known bugs, even though they may certainly be in here somewhere.
+ * Possible performance improvements could be to remove the div in
+ * bitmask_overlap_pos() and to implement wider stripes if the masks used
+ * are wider than 64 bits on the average.
+ *
+ * Performance of the various functions goes something like:
+ * (relative timings, smaller is better)
+ *
+ * bitmask_overlap() 1.0
+ * bitmask_overlap_pos() 1.3
+ * bitmask_overlap_area() 1.6
+ *
+ * For maximum performance on my machine I use gcc with
+ * -O2 -fomit-frame-pointer -funroll-loops
+ *
+ *
+ * If you can make these functions faster or have found any bugs please
+ * email Ulf Ekstrom, ulfek@ifm.liu.se
