Subject: Patch #1421422 - Backdrop image patch started by Linus, finished by
 me.  Adds ability to set backdrop images for file browser and menus (store
 full-screen bitmaps in /.rockbox/backdrops/) and also the ability to set a
 full-screen background image in a WPS using the %X|filename.bmp| WPS tag. 
 Currently only implemented for targets with colour LCDs.
