make recovery UI images more general; allow for installation animation
Change some of the UI parameters (# of indeterminate progress bar
frames, fps, etc.) from #defined constants to variables that can be
set by the device-specific recovery_ui code (via a new function).
Support overlaying different images on top of the base installation
icon to animate it. Make the FPS control more accurate.
