- clamp scissors fully to avoid NVidia's awful drivers locking up the entire system if they end up out of bounds - perform buffer clears as part of the render pass. this puts some restrictions on how FRenderState.Clear can be used - add an offset uniform to the present shaders so the vulkan target can flip the image during presentation
