2020-12-13	Fix weird Swing+Twist decomposition with noncanonical quaternions.	Alexander Gavrilov
	It turns out that after the fix to T83196 (rB814b2787cadd) the matrix to quaternion conversion can produce noncanonical results in large areas of the rotation space, when previously this was limited to way smaller areas. This in turn causes Swing+Twist math to produce angles beyond 180 degrees, e.g. outputting a -120..240 range. This fixes both issues, ensuring that conversion outputs a canonical result, and decomposition canonifies its input. This was reported in chat by @jpbouza.

	No functional changes.
2020-11-30	Fix T83196: bad matrix to quaternion precision near 180 degrees rotation.	Alexander Gavrilov
	Adjust the threshold for switching from the base case to trace > 0, based on very similar example code from www.euclideanspace.com to avoid float precision issues when trace is close to -1. Also, remove conversions to and from double, because using double here doesn't really have benefit, especially with the new threshold. Finally, add quaternion-matrix-quaternion round trip tests with full coverage for all 4 branches. Differential Revision: https://developer.blender.org/D9675
