Render this widget.
The default implementation uses the 'GetTexture()' method above. By overriding this method it is possible to define widgets with a custom SDL rendering procedure, which may be more efficient than preparing a single texture containing the complete widget.
It is allowed to pass 'ren == NULL', in which case all textures and internal data structures are (re-)calculated, but nothing is actually rendered.
Reimplemented from CCanvas.
