The default snap behavior to perform on tools and cursors is to the final geometry and not edited geometry. In snapping to edited geometry, there are some specific behaviors that are not convenient in some cases. For example the general occlusion test of X-Ray geometries during dragdrop. This fix also resolves a regression for tools like measure and placement that were also ignoring the snap to face in x-ray mode. Differential Revision: https://developer.blender.org/D13410
