+ * xcompmgr.c: (sum_gaussian), (make_shadow), (root_tile),
+ (paint_all), (map_win), (unmap_win), (determine_mode),
+ (configure_win), (circulate_win), (main):
+ Track whether cliplists have changed and avoid computation when not.
+ Shrink shadows.
+ Speed up shadow construction a bit by using memset.
+ Eliminate useless INTERVAL code.
+ Use XSync after paint_all to gather more events per update.
