Subject: [#21433] Angular rotation snap issue, final value set is not snapped
 - SVN 27250 and 2.50A1

Proper fix for this. Moving special mouse input stuff to custom callbacks (this also makes the per transform main functions a bit cleaner).

It also fixes the operator property (value) for shear and warp.
