InheritanceCanvasBackground Inheritance spark.components.Group

Handles the background for the canvas.

Operates in one of two modes: (1) draws a rectangular fill if the "backgroundColor" is not NaN. (2) Fills a BitmapImage with the supplied "transparentSource" data if the "backgroundColor" is NaN (transparency).

Note, drawing the transparent checkerboard using the flash vector graphics engine is crazy slow. Using a BitmapImage that repeats its fill is much, much faster.
