set_stylesheet
Description:
Sets a CSS stylesheet to use for an SVG document.
The css.length argument is mandatory; this function will not compute the length of the css string. This is because a
provided stylesheet, which the calling program could read from a file, can have nul characters in it.
During the CSS cascade, the specified stylesheet will be used with a "User" [origin](https://drafts.csswg.org/css-cascade-3/cascading
-origins).
Note that `import` rules will not be resolved, except for `data:` URLs.
