i would also like to see this. i skimmed over the meeting minutes and the
coders all said that eulers won't really work... but when i still used maya
i always animated with eulers and there never seemed to be much of a
problem. there must be some solution i guess? maybe some way to internally
still use quaternions and only use some euler conversion for editing?
