RFC 1 stage: Improve maintainability of the cursoir painting code
- Turned the mouse cursor painting code into a macro for more maintainability - Dropped mouse cursor painting in 8bit mode - Removed log when dropping frames - Free the shared memory segment on close Originally committed as revision 7295 to svn://svn.ffmpeg.org/ffmpeg/trunk
