FreeRDP/libfreerdp/gdi/gdi.c
Norbert Federa fa2086686b some performance fixes 
- draw only the updated region in the gdi and x11 surface bits implementation
- don't repeatedly call IsProcessorFeaturePresentEx in rfx rlgr decoder
- fix ugly and unaligned profiler print layout and remove an unnecessary value
