Revert "Straighten out zoom and border-image"

This patch reverts https://codereview.chromium.org/1819083004 patchset

Fixing SVG zoom in border-image unfortunatly broke gradients
instead. There is a difference in how scale it applied for
zooming. For SVG a source rect (unzoomed) <-> destination rect
(zoomed) scale factor is computed and used for scaling. For gradients,
the source and destination rect are always the same (both zoomed). The
individual gradients stops are zoomed instead.
