tickit_rectset_subtract - subtract a region from a rectangle set
#include <tickit.h>
void tickit_rectset_subtract(TickitRectSet *trs, const TickitRect *rect);
Link with -ltickit.
tickit_rectset_subtract() ensures that the regions stored by the
rectangle set do not include the area given by rect. To do this, it may
have to split one or more of the existing regions into smaller fragments, and
so may result in more regions being stored.
tickit_rectset_subtract() returns no value.
