[Sugar-devel] Preview field in web activities

[Suraj K S]

canvas.toDataURL() throws the Security Exception in both paint-web and
markdown activities.

I tried it on an earlier an activity which i made some time back,
https://github.com/surajgillespie/myactivity
In this case it works fine.
I'm able to get the image in a base 64 encoded string.
