Embryon functionnality for snapping.
- Only snaps to grid on translations (grab)
- Transform constraints are supported but header display is wrong.
- Can be turned on/off in the Object/Mesh header menu under Transform Properties (tentative spot, will have to integrate better and in other object type menus too)
- Can be turned on/off during transform with ` (Back Quote, also tentative)
This is, of course, very much Work in Progress.
This implements part of the structural ideas for the transform cleanup I've been juggling around with.
