> This code worked before refactoring. Why did we have to make all those changes in ImageBuffer::copyImage just to restore behavior to how it was before? The previous patch didn’t have ImageBufferCG.cpp changes.

The previous implementation only really worked by accident, because we had erroneously allocated a buffer at 4x in DragImage and incorrectly scaled it down in ImageBuffer::copyImage, but the two bugs cancelled each other out.
