Rather than changing the size of the child elements (relaying out text and potentially changing glyph shape and position due to pixel snapping), apply the stretch effect as a compositing effect - render the children to a texture and stretch the texture. If we end up using an image shader to apply an custom shader we'll need to do this anyway.
