Use openGL to render HTML 5 canvas

The rendering speed of HTML 5 canvas is not good enough for CPU limited device ARM11, Cortex A8 (for dynamic content obviously ).

Samuel demonstrated the speed of HTML 5 canvas with the graphic system openGL. This graphic system is still considered experimental and has negative side effects when considered outside canvas alone.

When the other layers are also composited with openGL, it would make sense to render the canvas directly on a Framebuffer object (FBO).

This project is about:
-render canvas with openGL
-measure the performance gain and loss depending on the use case
-find an acceptable solution for the pixel read-back API
