When picking we need to disable dithering to be sure that the hardware will not modify the colors we use as actor identifiers. Clutter was manually calling glEnable/Disable GL_DITHER to handle this, but that was a layering violation since Cogl is intended to handle all interactions with OpenGL. Since we are now striving for GL vs GLES to be a runtime choice we need to remove this last direct usage of GL from Clutter so it doesn't have to be linked with GL at build time.
