It can now automatically load the correct subimage from a strip (assuming the strip is in the correct order) by giving a tag for the 2nd param. example: %xd(F, %mp) which is equivilant to %?mp<%xd(Fa)|%xd(Fb)|%xd(Fc)|%xd(Fd)|%xd(Fe)> You can also set the subimage offset.. i.e %xd(E, %mm, -1) which means "show nothing for the first value of %mm and use the bitmap strip for the remaining values" if a tag+offset is <0 or greater than the number of subimages in a strip he image is cleared (I'm open to changing this if someone has a better idea) cabbiev2.176x220x16.wps is an example of how to use this git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27717 a1c6a512-1295-4272-9138-f99709370657
