Subject: [PATCH] Three cosmetic fixes;

- Mesh editmode, draw 'bleeding edges' works again for subsurf (not optimal)
- New draw method (again!) for armature-add-bone loop. Should work now! Is
  also nice for cpu this version
- Draw screen edges (black lines inbetween windows) should not draw leftmost
