GLMixer Code

Bugs fixed (repeated session loading when switching, misplacement of Log widget when restart, misplaced context menu on property browser, thread priority before started).

Edited wiki page Screenshots through web user interface.

oops.. seemed a bad idea to lower priority of encoding thread...

Performance optimization (maybe...) by using repaint() slot instead of update() for main QGLWidgets and lowering priority on some threads.

Added properties to inform about SVG source and Capture source resolution.

update icons for split Gamma Levels dialog.
