Bug 1323962 - Should support CSS transform for mask r=longsonr SVGElement::PrependLocalTransformsTo doesn't take CSS transform into account, we should use nsIFrame::GetTransformMatrix instead.

Bug 1547209 - Compute transform matrix directly in nsSVGUtils::GetTransformMatrixInUserSpace r=longsonr Since now most CSS transform related bugs are fixed, it's clear that the purpose of nsSVGUtils::GetTransformMatrixInUserSpace() should solely be to replace SVGElement::PrependLocalTransformsTo(eUserSpaceToParent). After fixing Bug 972041, the only other usecase (Bug 1247218) no longer exists. OTOH, there is a problem when the parent has a viewbox transform, in that case, SVGElement::PrependLocalTransformsTo() doesn't include it, but nsLayoutUtils::GetTransformToAncestor() does. In fact, it's much easier to compute the transform matrix directly based on the implementation of nsDisplayTransform::GetResultingTransformMatrixInternal(), which is also the function internally called by nsLayoutUtils::GetTransformToAncestor(). In particular, we don't need to look at 3D stuff since our matrix is inherently 2D.
