Log Message:
-----------
Add support for png and jpg exports with option `output: 'blob-promise'`
- This doesn't seem to improve the image size limits of the browsers. For PNG:
Safari and Chrome handle around 16,000 x 16,000 images, while Firefox handles
around 10,000 x 10,000 images. This is unchanged from the manually-generated
blob from base 64.
- This does not seem to speed up image exports for blobs. However, the promise
option does not block the main browser execution thread. This could be useful
for showing a loading spinner icon while the blob is being generated.
- Add tests to the test page for exporting png. Include FileSaver.js in the
debug page for testing that downloads work properly.
Ref : For blob image exports, use `canvas.toBlob()` where available #2208
