GPU: If a custom-sized layer is to be rendered first, GPUEngineBase::_TransitionLineNativeToCustom() will do a line clear instead of an upscaled line copy.
- Since this is a very common occurrence in many games, and since doing a clear is faster than doing an upscaled copy, this should give a small performance improvement for the larger framebuffer sizes.
