Add the ability to use bitmap strips (a single .bmp file containing many images of the same dimensions, tiled vertically - similar to icon strips) in the WPS. The %xl tag now has an optional "number of subimages" parameter, and the %xd tag has an optional "subimage to display" parameter (a-z,A-Z - allowing up to 52 sub-images). So for example, a bitmap with 10 subimages is loaded with %xl|M|volume.bmp|134|153|10| and then this can be used in a conditional as %?pv<%xdMa|%xdMb|%xdMc|%xdMd|%xdMe|%xdMf|%xdMg|%xdMh|%xdMi|%xdMj>.
