Sets a [class@StyleScheme] to be used by the buffer and the view.
Note that a [class@StyleScheme] affects not only the syntax highlighting,
but also other [class@View] features such as highlighting the current line,
matching brackets, the line numbers, etc.
Instead of setting a %NULL @scheme, it is better to disable syntax
highlighting with [method@Buffer.set_highlight_syntax], and setting the
[class@StyleScheme] with the "classic" or "tango" ID, because those two
style schemes follow more closely the GTK theme (for example for the
background color).
