[raster]: need more pictures and possibly also PL/Javascript

[robe]

I'll try to find some to demonstrate particularly with the ST_MapAlgebra and ST_Reclass which I seem to use a lot of. It just irritates me a bit that we have all this great functionality and not flaunting it in a more dramatic way.

I'd also like to experiment with using plv8 for writing Map Algebra arg reference functions.

I suspect it will be faster than plpgsql in many cases. My sample tests seem to suggest for numeric processing it can be orders of magnitude faster than plpgsql and will be more appealing to your standard programmer crowd than plpgsql. I just haven't grokked how to handle arrays in it yet. Or if it is doable with 1.3.

Bborie and Pierre -- would you mind me throwing some PL/Javascript function examples in the docs. Thinking of putting it in:

With link to it from ST_MapAlgebra.

Don't ask! ;-) Go nuts!
