Unknown W. Brackets 7cef06c191 softgpu: Track dirty vs really dirty per buffer.
When games draw and display with a frame lag, it becomes important that we
indicate really dirty for the correct buffer.  Since some triple buffer,
this attempts to track at the buffer level using 1024 byte granularity.
