Some devices may require DMA transfers to flush the updated buffer areas prior to flipping. For those devices we track the areas that require flushing prior to the next flip. For devices that do not support flipping, but require flushing, we'll simply flush after updating the front buffer. This also adds a small optimization that skips these steps entirely for a screen that doesn't have any updates that need to be rendered.
