 I implemented caching of OSD images to memory and disk. Result is a quite
 remarkable improvement
 in channel change speed for me. Without this patch, a channel change takes
 about 11 secs, with
 the patch it's about 7 secs. It's still way too long for an enjoyable
 channel surfing session,
 thus I'll probably continue profiling and optimizing it at some point.

 I suggest to apply this also to 0.19 as the channel change slowdown is
 clearly a regression from 0.18.
