We should not do anything to encourage the mixing of 2D & 3D
rendering via different APIs. The required synchronization between the
APIs will kill performance. People should be encouraged to draw
everything in their canvas with WebGL.|

It's not at all clear from the HTML5 spec if you are supposed to be allowed to get multiple different contexts to the same canvas (or else I missed that part of the spec that makes that clear) This seems like a valid thing to want to do. var c3d = canvas.getContext("webgl"); var c2d = canvas.getContext("2d"); var csvg = canvas.getContext("svg"); Draw3DWorldWith3dContext(c3d); DrawTextLabelsOfThingsIn3DWith2dContext(c2d); DrawUIWithSVG(csvg) I know that so far WebGL has assumed only 1 context is allowed but maybe we should get a definitive answer.
