Incorrect clamping on SVG masks when root element is not located at (0,0)

Summary Incorrect clamping on SVG masks when root element is not located at (0,0)

Currently, when creating the mask image, we clamp its rect by svgRoot->contentBoxRect() (equivalent to bounds). However, the mask image origin is absolute, not relative to the svgRoot. Therefore, when the origin of svgRoot is not at (0,0), the clamping is incorrect. If we instead clamp by svgRoot->frameRect(), the absolute frame of the svgRoot, we get the expected results. Test case attached (expected: a quarter of a blue circle, actual: nothing!), patch forthcoming.
