Display buffer flips are now triggered by the CPU thread through the Video_UpdateXFB function. This is a fairly significant change of behavior, but it improves performance.
Also, render target code is cleaned up. Post-processing shaders now work with multisampling and Real-XFB mode. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@3545 8ced0084-cf51-0410-be5f-012b33b47a6e
