Enabled HW acceleration for CopyRegion(). Tested on Haiku and it works. I also implemented FillRegion and InvertRegion. But using different acceleration hooks after one another freezes Haiku, app_server, the accelerant or whatever. I have no clue about accelerants, so if a knowledgable someone would have a look at AccelerantHWInterface.cpp, that'd be great. The software cursor stuff has a cosmetical bug with regards to CopyRegion() too, I don't understand it yet. I also tried to improve StringWidth() and DrawString() preformance. I confirmed that the glyph cache is actually used, but AGGTextRenderer::RenderString() is a dog.
