Embed images into the infinite 2d plane, i.e. make them bounded rectangles with a location in that plane. We had a start on that with the operators for projective warp, storing the origin point in the user-meta data. This information is now in the C level structures.

This commit provides the basic change, plus new accessors for the geometry data, and updates all users of said geometry data in C to use these new accessors.

The semantics of the various operations which could make use of the location information has not changed yet. This is for future commits in this branch. check-in: 1da2e834b8 user: andreask tags: infinite-plane

Having worked through and vetted most of the code in the parental branch I want this code in the main branches, for regular use.

But there is still unvetted code, namely the 'filter::cleanup' and the higher-order image registrations (rotation, scale, affine, find-object), where I have run into roadblocks of understanding myself, and where I defer to Kevin for vetting.

To get the vetted pieces into the mainline, without having the unvetted parts this commit is made. It removes the unvetted pieces, puts them into a new branch, and this new branch will then be integrated with "works-for-critcl-2.1" and then "works-for-critcl-3".

The code is not lost, of course. It is still in the "x-smsaurabh" branch, and when Kevin has worked through it, it can then be integrated also. Leaf check-in: d7015891a3 user: andreask tags: integration-stage
