ImageQualityController considers the image size and layout size when
computing which resampling algorithm to use, but did not account
for the current transform. This was noticeable as 'bouncing' when
scaling an image directly with a transform.

This patch incorporates the context's CTM (which includes scale
but not zoom) into the resampling calculation. Because the
ImageQualityController runs on a 500ms timer, a manual test
has been added.

* Source/WebCore/rendering/ImageQualityController.cpp
(ImageQualityController::interpolationQuality): Rename "size" to "layoutSize
(ImageQualityController::chooseInterpolationQuality): 
(1) Move "unzoomed" image below
(2) Moved up "AffineTransform" and "contextIsScaled" before resizing condition 
(3) Introduced "scaledImageSize" and "scaledLayoutSize" and replace usage of "size" with "scaleLayoutSize" 
(4) Replace use of 'size' with 'scaledLayoutSize'
* ManualTests/image-resampling-with-scale.html: Added Test
