 // Prerender tests work as follows:

 // A page with a prefetch link to the test page is loaded.  Once prerendered,
 // its Javascript function DidPrerenderPass() is called, which returns true if
 // the page behaves as expected when prerendered.
 //
 // The prerendered page is then displayed on a tab.  The Javascript function
 // DidDisplayPass() is called, and returns true if the page behaved as it
 // should while being displayed.

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.
