Draws a subset of a loaded SVG handle to a Cairo context. Drawing will occur with
respect to the @cr's current transformation: for example, if the @cr has a
rotated current transformation matrix, the whole SVG will be rotated in the
rendered version.
An element's id within the SVG, or %NULL to render
the whole SVG. For example, if you have a layer called "layer1"
that you wish to render, pass "##layer1" as the id.
