My first impression is that the library mixes many Concepts, that can easily be separated. The first is of a display matrix, the second is of an image. Others .. Points are Geometric Concepts. Colour is a Concept which too could stand alone. Cursor (locator) is useful to a matrix

The concept of an display matrix could be applied elsewhere, where elements could be for example text characters. An image can also be comprised of vector graphics, but this subject is not touched upon in any serious way.

Colour would be useful in Vector graphics, but would deserve its own library and I would expect to see the interface more user friendly with mappings to commonly used colour systems such as those in HTML, SVG and VRML.

The domain that the library can be used in is very narrow. To be seriously used for image recognition as was previously suggested an application, my guess is that the library would need the ability to apply arbitrary transforms, including other than 90 degree rotations, and interpolation of points, stereoscopic vision etc.

As it stands the only use I can see is for touching up photos, and that is my problem with it , the domain is too limited. I would suggest revisiting the Concepts ,extracting them and then making sure that each would stand on its own. That would be a more interesting and widely useable set of libraries.

library, exactly. It's too large of a beast that should be broken down into several smaller stand alone libraries that could be repurposed to various tasks.

I agree that would be ideal; however, how many library authors have had the foresight to anticipate all those "varioius tasks" you describe, not many. Most of these "other uses" of a library are discovered later by accident. In the abstract, give these compenents you see a place to "live" and mature for a while, and then pull them out later when these "other uses" are discovered. You could have expressed this same concern with many of the other libraries that have been approved on boost.
