Broken: 2.71 RC2

Short description of error
Snapping vertices with a subserf modifier doesn't work very well in RC2.

Exact steps for others to reproduce the error

  1. Open
    auto_merge.blend479 KBDownload
  2. Press G and hold Ctrl while moving the cursor over one of the vertices on the cube. In 2.68a it's super easy to get it to work, but in RC2 it almost never snaps.

@Campbell Barton (campbellbarton) I see now. I didn't realize the snapping behavior has been improved between 2.62 and 2.71 to use the deformed edit cage. Very nice addition, thanks to whoever added that :)

However, I'm still not quite sure this is the most useful behavior..
Maybe when snapping with modified edit cage enabled, perhaps there should be an option to snap to the true position of the geometry instead?

So in the case of the vertex snapping to the modified edit cage, with the cursor on the apparent, modified location of the target vertex, the vertex being transformed would go to the true (unmodified) location of the target vertex.

Wait, I'm confused..
Where you perhaps thinking of T40680? I was thinking I was writing about that bug when I wrote the above comment..

If not, then I fail to see what auto merge has to do with this.. (I mis-named the .blend because I got slightly mixed up on which file was which when writing T40680 and this report)

Mistakenly confused this report with the T40680, re-opening.

Looks like this is a regression caused by rB7b5fe4f316234022a0ab761b694cd459ce98db2d
