YUV to RGB shader

Hey, I'm a developer on Roundabout - Alexander pointed me to this bug report.

It looks like our YUV to RGB shader is failing to compile properly on these
drivers. I've attached the source for this shader to the bug report to help you
track down any compilation issues, let me know if there's anything else I can
attach to help track down this issue.
