Expand description
Set the drawing scale for rendering on the current target.

The renderer for which the drawing scale should be set.scaleX

The vertical scaling factor
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.
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.
