richard wallis 9b644cd0a4 FMac Startup movie stuttering:
1) Change FSlateLoadingSynchronizationMechanism busy wait to yeild on destory and reduce sleep on thread exit wait.
2) Optimization: Remove busy wait blocking call on load next movie - make it async again.
3) Optimization: Don't do double texture data copy - which it seems to always do if it has another frame ready - copy straight to target texture (reduces CPU time by about 30% total in its ::tick() function.
