AFAICT, no browsers have yet implemented the modifications to the Canvas
spec from March of 2012. Can anyone confirm if that's the case? Any

What is really meant here by Canvas GPU acceleration?
This means use GL/D3D to implement the 2D canvas drawing primitives; but
what really matters here, is that this requires using a GL/D3D

I’ve implemented some polygon objects for my book that I can drag around in
a canvas. I detect mouse clicks in the polygons with the isPointInPath()
