Rather than modify the transform of the parent (which could change independently), this adds a new override element_transform() where element specific tranfroms can be applied. This will always stay in sync with the attributes. A ref test comparing a .svg and .html version of the same file is added as due to differences in attribute parsing order, the .svg version was previously drawn incorrectly. Fixes #20859
