Use contents scale even if the layer's transform is not affine

[Title] Use contents scale even if the layer's transform is not affine
[Issue#] P131001-01728
[Problem] The image of 3D transform layer is not clear
[Cause] Always use contents scale of 1 when the layer's transform is not affine
[Solution] Modify to use contents scale even if the layer's transform is not affine
