I'm trying out Eli Grey's awesome filesaver implementation to download canvases as a PNG image.
It's working well on most platforms, but I've hit a snag on Chrome on the iPad - it just opens a new tab that remains blank.
I do have a fallback for browsers that can't handle blobs, so I'm hoping there's some feature detection I can do to recognise when I might need to use the fallback.
Any suggestions?
