Sergey Sharybin 120c0659ed Camera tracking fixes:
- Fixed incorrect memory access on distoritons more than 128 pixels
- Do not use UNDO operators flags for delete proxy operator (files can't be restored form disk),
  and also do not use UNDO for set as background operator (background images are storing in
  3d viewport which isn't getting re-loaded on undo which can lead to incorrect users count
  of movie clip user).
