I think we should deploy this in at least one place to make sure it works and
is tested.  I think this patch is OK as is, but I'd rather see it used in at
least one of the places where we already do this by hand.  For example, the SVG
viewport code does this kind of thing.

SVGPaintServerGradient:
    TransformationMatrix matrix;
    if (gradientServer->boundingBoxMode()) {
        matrix.translate(maskBBox.x(), maskBBox.y());
        matrix.scaleNonUniform(maskBBox.width(), maskBBox.height());
    }

TransformationMatrix SVGPreserveAspectRatio::getCTM(double logicX, double
logicY,

There are many other examples in the code.  Not all of them would need to be
deployed to for this to be tested. :)
