Normalize should not crash on zero quaternion #19

Closed crertel closed 5 years ago

crertel commented 5 years ago

Quaternions of norm 0 cause the current normalize implementation to blow up, which is no good.

We should fix it to return a 0 quaternion in such cases, and maybe add a normalizeStrict that explodes otherwise.
