[gdal-dev] RFC 39, layer algebra in trunk

[Ari Jolma]

Folks,

I've committed the layer algebra stuff into trunk in changesets 24736 - 
24739. The last one is the initial test code.

I've also started a wiki page for describing the method set in more 
detail http://trac.osgeo.org/gdal/wiki/LayerAlgebra (linked to page 
http://trac.osgeo.org/gdal/wiki/CodeSnippets since that seemed to me as 
the best place).

Best regards,

Ari
