Trying a little something with the MMB behavior.

Browse Source 
Constraint selection is now based on mouse motion (instead of pointer position).

What that means is that if you simply click MMB, it works exactly like it did with old transform (in 90% of the case, the last 10% is when MMB click was unpredictable in old transform because of extreme viewport orientation)

Also, since this means you don't really have a referential on which to base yourself, it draws a dashed line representing the mouse motion, starting at the center of the axis lines.


Please test and discuss, if this is better than before or not.
