Fix density corrected painting in DrawTiledBackground single-tile path

GraphicsContext::DrawImage(...) (and related machinery like the various
Image::Draw implementation) have different requirements on the source
rect from GraphicsContext::DrawImageTiled(...) so the two code-paths in
DrawTiledBackground() need to use different variants of Image::Size()
when computing the intrinsic tile size.
This moves the single-tile path closer to that in PaintFastBottomLayer()
as well.

The computation of tile scale is pushed into the generic path because it
is not used in the single-tile path (ComputeSubsetForBackground()
computes an equivalent there).
