What steps will reproduce the problem?
1. Install attached CRX
2. See black background instead of a fully transparent one

What is the expected output? What do you see instead?
The background should be transparent.

If it's a regression please make beta.

Not a regression.

Investigated, and it seems that even when drawing raw alpha=0 during paint in
browser_frame_view, you get black. Either I'm missing something or it's plain
unpossible. Either way, punting for now.

Have to roll this back due to major Ts hit. If we can figure out how to do this
without a speed regression... Not going to be M5.

Avi please also take a look here:
https://code.google.com/p/chromium/issues/detail?id=24693

I think the decision from UI folks was that we don't support transparency in themes.

So an artist made a theme with transparency and now all transparency is disallowed? :(

dmaclach turned the window transparent accidentally a while ago and a) startup perf 
suffered and b) mouse scroll events also scrolled the window behind the chrome 
window. if you re-enable transparency, check that you don't regress either of those

dmac claims UX says no. Closing; if you want to push this through get UX to approve
and re-open.
