Hi Jordi, (and mono devs)
Mainsoft wish to invest some effort in testing System.Drawing.
We wish to enhance the test suite with an image compare component which will
compare the difference between the expected .NET image and the mono image. 

The comparer (which we just started prototyping it) will be customized and
produce a result according to several algorithms:
* Prior to compare: format, size, colors, resolution
* Color - strip boarders; compare histograms to get top colors and areas. 
* Edge Detect - edge detection, and line generation, compare line lists.
* Histogram to detect shapes
* FFT (or cosine transform) of sub-regions or the whole image.
* Tangent space Vectors

* I appreciate your inputs?
* Do you recommend on a curtain GPL library?
* Does anyone have such task in his TODO list?
