[SVGMobile12] SVGSVGElement::createSVGMatrixComponents

The SVG 1.1 DOM has a matrix creation method of SVGSVGElement that 
corresponds to the methods of other base types, namely:

	SVGMatrix createSVGMatrix();

The SVGT 1.2 uDOM replaces this with createSVGMatrixComponents(...), 
which seems like a needless incompatibility that authors will need to 
deal with when adapting 1.1 content to 1.2t.  I suggest switching back 
the 1.1 DOM method of matrix creation.
