* The drawing coordinates are scaled by the x/y scaling factors
* before they are used by the renderer. This allows resolution
* independent drawing with a single coordinate system.
* \note If this results in scaling or subpixel drawing by the
* rendering backend, it will be handled using the appropriate
* quality hints. For best results use integer scaling factors.
