this commit makes very slowly the gtk emulation when selectin "none" in output rasterization..

computers with no opengl support and multiple usages of XV video or lacks of them, are not able to use with good performance...

there's two solutions:

  1. revert extensive usage of cairo software rasterization
  2. autodetect free port on XV layering of X11 subssystem (more complicated)

and example, if user has a unichrome or SYSchroma GPU, not has support of OpenGL, so falback to XV..
but if user has some settings on screen (brigth r saturation) throught XV, snes9x can able to run (black screen in output)

i opened a issue as #58 due real linux GNU users that do not have firmware access cannot play wth this emulator
for cases such modern SiS , Matrox Pharphelia (no GNU xorg modules available normally), also for VIA, 3DFx, old Intel and Voodo GPU's
those GPU's lacks of VX acceleraded and also lacks of OpenGL support on linux, this commit mades performance decreaing for these users
