Use Image::SizeAsFloat() and unsnapped rectangle in ImagePainter
The pixel-snapping of the destination rectangle can end up distorting
the geometry use for painting an SVG image preserveAspectRatio is used -
the larger the aspect ratio, the larger the error.
By passing the unsnapped rectangle to LayoutImageResource::GetImage, and
using Image::SizeAsFloat() to compute the source rectangle of the image,
e can minimize the error and allow the Image in question (an SVGImage)
to perform compensation for the difference in aspect ratio between the
snapped and unsnapped rectangles. This means that the painted result
will better approximate the intended rendering.Also clean up accesses to the LayoutImageResource and ImageResourceContent
by adding and using local variables for them.Bug: 812239
