FBO blit

FBO blit in (and out?)

See #13 (comment)

This is implemented in https://github.com/GameClay/syphon-framework/tree/PSW-OpenGL3

Not considering this urgent. You can access the texture backing the internal FBO using SyphonServer's -newFrameImage, so maybe use the server's FBO instead of your own FBO that you then blit?

Arguments for welcome.

This needs some research as some reports indicate Blit is slower than a quad render to an FBO.

Also we have slight concerns of pixel format (say RGBA vs BGRA formats let alone float / 16 to 8 bit conversion, etc)
