Modified:

   trunk/mythtv/libs/libmythui/mythimage.cpp

Log:

Fix the image cache to only consider items otherwise unused to be "in" the cache for memory accouting purposes.  Earlier it would consider all items in the cache to be "in", so the cache would fill up with things like menu watermarks (which are always referenced elsewhere, so shouldn't be considered), and essentially refuse to cache any other items.

This, like the rest of the UI code, assumes it will only be called from the main Qt thread.
