Add a bug for this. Feels pretty bad - even if you get to a situation where
trybots pass, it may break on other people's machines. Is there a way to
determine whether hardware support is enabled for the current platform at
runtime, and early exit if it's not supported?

[mmenke, 2011/04/19 20:00:01]

Bug filed.  I couldn't find a way to do so, but I'm sure it's possible.  The
renderer process apparently knows not to send us compositing requests, somehow,
afterall.
