Fixes for backbuf selection logic

- Fix ED_view3d_backbuf_sample_rect, r_dist was set completely wrong.
- Avoid duplicate calculations picking the nearest edge.
- Bias against picking selected edges is now optional.
- Remove unused callback reading the backbuf.
- Remove unused strict option picking vertices.
