VideoSoftware: Added Real XFB support.

Browse Source 
Massivly increases the accuracy of VideoSoftware, if it's going to be slow, it
might as well be accurate.

 * Fixes flickering issues in games which double render to get Hardware AA, like the Peach's Castle tech demo.
 * Rouge Squadren 2's Cantina Intro doesn't flicker anymore, but it duplicates the top half of the screen onto the bottom.
 * Any games which need RealXFB support should now work in Video Software
