Development Thread Testing needed for GLExtensions branch

[KHg8m3r]

No problem using x86 or x64 using high performance Nvidia card. However, using the HD 4600, the bugs from last time show back up. With no AA or AF, I can hit 3x IR with slight slowdowns (98% speed, lose one or two fps), either backend. On 1.5x IR, I can add some AA or AF, no problem. Go to 2x IR and add any AA or AF, and bam, massive slowdown and that Sonic Colors glitch comes back, only on OpenGL.
