I've been setting up a small framework for rendering positionable and animated graphics onto a <canvas> element - primarily to help my understanding of it.
I downloaded a random sprite sheet off the internet for testing - it has a transparent background which seems to render fine in Chrome, on my iPhone and Safari.
This is the demo: http://martywallace.com/simplecanvas/
In Firefox however the transparent sections of the sprite load as white, which ends up looking like this:
Is there a Firefox-specific way to enable transparency, or is it not supported?
