Reduce glcalls noise and explicitly disable dithering and multisampling if not requested
Explicit disabling of multisampling doesn't make noticable difference, but renderdoc now doesn't report it as enabled.
Writing uniform buffer, disabling depth test, then writing another values to uniform buffer and enabling depth test back is kinda pointless.
OpenGL enables dithering by default, which on some hardware decreases performance.
