Will be set to #TRUE if the toplevel SVG has a <literal>width</literal> attribute
Will be set to the value of the <literal>width</literal> attribute in the toplevel SVG

Will be set to the value of the <literal>height</literal> attribute in the toplevel SVG
Will be set to #TRUE if the toplevel SVG has a <literal>viewBox</literal> attribute
Will be set to the value of the <literal>viewBox</literal> attribute in the toplevel SVG

Queries the <literal>width</literal>, <literal>height</literal>, and <literal>viewBox</literal> attributes in an SVG document.
If you are calling this function to compute a scaling factor to render the SVG, consider simply using rsvg_handle_render_document() instead; it will do the scaling computations automatically.
As an example, the following SVG element has a <literal>width</literal> of 100 pixels and a <literal>height</literal> of 400 pixels, but no <literal>viewBox</literal>:
|[ <svg xmlns="http://www.w3.org/2000/svg" width="100" height="400"> ]|
Conversely, the following element has a <literal>viewBox</literal>, but no <literal>width</literal> or <literal>height</literal>:
|[ <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 100 400"> ]|
Note that the #RsvgLength return values have #RsvgUnits in them; you should not assume that they are always in pixels. For example, the following SVG element will return a width value whose <literal>units</literal> field is RSVG_UNIT_MM.
|[ <svg xmlns="http://www.w3.org/2000/svg" width="210mm" height="297mm"> ]|
API ordering: This function must be called on a fully-loaded @handle. See the section <ulink url="#API-ordering">API ordering</ulink> for details.
Panics: this function will panic if the @handle is not fully-loaded.
