- Removed double buffered gpu cmdbuffer (might be added back later) - Added a global gxCmdQueue which by default is configured to run commands as they arrive (in the future it might be double buffered) - Added C3D_FrameSync for explicitly waiting for "vblank" - Repurposed C3D_FRAME_SYNCDRAW to perform C3D_FrameSync - Added C3D_FrameSplit for splitting/submitting the gpu cmdlist in the middle of a renderqueue frame - C3D_RenderTargetSetClear is still supported, however it's unofficially deprecated (it's performed after drawing/transferring instead of before drawing, which is pretty counter-intuitive) - C3D_RenderTargetSetOutput is explicitly NOT deprecated since it's necessary to avoid screen tearing when transferring to the screen framebuffers (this stems from a Nintendo design flaw where screen swap processing is done immediately after GX transfers finish)
