Animated GIF not displaying in pub page, does appear in github readme

[sethladd]

URL: https://pub.dartlang.org/packages/progress_hud

Github: https://github.com/rcpassos/progress_hud

Not sure if this is a systemic issue?

Expected result: should see the animated gif in the pub page.

Github is tricky here. The original url is being rewritten by their markdown engine:

• https://github.com/rcpassos/progress_hud/blob/master/progress_hud.gif into:
• https://github.com/rcpassos/progress_hud/raw/master/progress_hud.gif (not the blob->raw change)

It is entirely feasible for us to detect and rewrite such urls, but if you are in a hurry fixing it, I'd also suggest to change the README to use the raw url.
