Summary

The original matrix_channel description didn't include the fact that the
property is read-only.

The original matrix_basis description stated it was an alternative
access, but didn't mention alternative to /what/.

Sybren A. Stüvel (sybren) retitled this revision from to Clarification of PoseBone.matrix_{basis,channel} property descriptions..

880	Tooltips should start with a capital Since you're making changes here, it's actually not correct that chan_mat is "before constraints". During the pose evaluation process (i.e. when constraints are being evaluated) this is true. However, once the last step before pose evaluation is completed, chan_mat gets populated with the "deform matrices" that the armature modifier uses instead (see blenkernel/armature.c 2163).

880	Are any Python scripts run in between those two processes? If not, then Python scripts only see one of the two uses, and we can keep things simple.

880	Nope. Python scripts don't get run. The only case where that may apply is if PyConstraints come back... but then how it works remains to be seen
