What is the intent of the getContext function on the <canvas> tag?
Should it be possible to get multiple simultaneous different contexts as
in?
var ctx2d = canvas.getContext("2d");
var ctxText = canvas.getContext("fancy-text-api");
var ctxFilter = canvas.getContext("image-filter-api");
ctx2d.drawImage(someImage, 0, 0);
ctxText.drawText(0, 0, "hello world");
ctxFilter.radialBlur(0.1);
?
OR
is canvas only allowed 1 context at a time?
In theory multiple contexts should be possible. E.g. we supported 2d,
opera-2dgame, and opera-3d for a while. However it seems that for certain
contexts, in particular webgl, using it together with other contexts is
not possible (for now anyway).
