Support toBlob() on canvas
Edge only supports msToBlob() currently. Please support standard toBlob().
Don McCurdy commented
An implementation of the `toBlob()` API would be useful in graphics libraries for asynchronously encoding the contents of a canvas. The lack of this API, and the mismatch with `msToBlob()`, have recently been part of issues like https://github.com/mrdoob/three.js/pull/14991.
Please implement this to spec including callback feature, because for large images or frequent use mstoblob blocks for too long making page unresponsive.
+1 please add support for HTML5 spec toBlob including image format and compression quality hint. Essentialy for some high performance graphics operations.
