GFX:
- FIFO changes - minor cleanup, code organization based on Nolan's changes - Minor code cleanup - CommandProcessor changes - Allow BP IRQ clearing for either raising or falling edges. - Revived old SetFifoIdle code Gets Pokemon XD to run, but will crash to any CPU-GPU desync. Other games like Metroid Prime, look happy with the new FIFO changes. Please report any problems. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@3984 8ced0084-cf51-0410-be5f-012b33b47a6e
