Patch no. 1 changes the matching algorithm. On images that I tested it gave the same or better results, but in theory there can be some regression with some images.
Patch no. 6 changes the written pto files because the original behavior was IMHO buggy.

Otherwise there are no changes for existing users.

Title:
  Stereo images alignment

Status in Hugin - Panorama Tools GUI:
  Triaged

Bug description:
  Hi,
  I tried to use align-image-stack for processing stereo images (taken from slightly different angle). Here are the modifications that I did:

  1. Two-phase control point matching - the patch adds second phase,
  where the points are fine-tuned on full-size image. This gives better
  results with comparable speed.

  2. stereo mode - the points are optimized only for Y (horizontal
  line). Horizontal shift of the control points is allowed. One vertical
  line is added to anchor the horizontal shift of the images. The patch
  also adds options to optimize distortion and image center shift.

  3. extra control points around the image edges - in stereo mode the image edges are interesting for "stereo window" alignment. The normal method generated too few control points near the edges. This patch forces additional points, which are then filtered by correlation and geometric pruning.
  I want to work on automatic "stereo window" alignment in the future.
