cc: Use ScreenSpaceTransform to determine content scale
ScreenSpaceTransform should be used to determine the ideal content
scale as TargetSpaceTransform will no longer be cached in transform
tree.
Because of the way sublayer scale works, the scale component of
TargetSpaceTransform is the same as the scale component of
ScreenSpaceTransform.
The switching results in a different behavior because of snapping
float transforms, thus a manual rebaseline is needed for layout test.
