Integrate friendly tips from Tor colleagues to make (or not) 4.5 alpha 3;
This includes removal of overloaded (but unused) methods, and addition of
a overlooked call to DataStruct::SetData(nsISupports, uint32_t, bool.)

8 ========= PLEASE KEEP THIS IN SYNC WITH test_animations.html =========
10 This test mimicks the content of test_animations.html but performs tests
11 specific to animations that run on the compositor thread since they require
12 special (asynchronous) handling. Furthermore, these tests check that
13 animations that are expected to run on the compositor thread, are actually
14 doing so.
16 If you are making changes to this file or to test_animations.html, please
17 try to keep them consistent where appropriate.
