[GRASS5] optri ?

[Andreas Lange]

Hi Markus, hi Bernhard,

optri was removed because of copyright issues that could not be resolved
to be compatible with GPL. So the message in the BUGS file about the
optri problem is obsolete.

With detri the license is ok, but there is a another library part of
detri that is not compatible with GPL. This part has to be removed and
changed to c standard library functions.

Next the detri library has a different structure than optri, so that a
simple search & replace or wrapping the library won't work. I have no
clue how much work this is and if/how detri can be adapted to GRASS. 

Generally i think that GRASS needs one library for computational
geometry that provides functions that operate on the GRASS data. If
detri is adapted to GRASS in the same way optri was this would be only
another 'hack' to provide some functionality for some stand-alone
modules, but not usable for general programming. 

I already wrote down what functionality IMHO is needed, if i find the
mail again i will check the text in for CVS.

cu,

Andreas
