Vertex snapping now works with backbuffered selection modes. Previously backbuffer sampling had no way to check whether or not the indices that it retrieved were selected or not. To resolve this I added two optional arguments to sample_backbuf_rect in drawview.c. The first argument tells the function that some additional testing of the retrieved index values needs to be done and the second argument is a pointer to a function to do the testing. findnearestvert() in editmesh_mods.c now makes use of this and passes sample_backbuf_rect() the appropriate argument when being used for vertex snapping.
