[Octave-patch-tracker] [patch #9000] Polygon functions for geometry/mapping package

[Juan Pablo Carbajal]

Follow-up Comment #6, patch #9000 (project octave):

Philip,

Lets go by parts. First lets finish merging your functions into geometry and
decide what to do with the ccw functions and thne lets go for polytri.

Many functions in the geometry package accept Nx2 arrays (x,y single matrix)
or two Nx1 (x,y separated arrays).

Is there a reason to keep this two modes inside polyclip, like performance or
something? If not, then I would really like to separate into two functions.
One to query the orientation of the polygon and one to do the actual
clipping.

Libraries that are packaged in linux distributions is better to have them as
external dependencies. If the library is obscure, not easily accesible or
can't be compiled automatically, then we can consider packaging it. In the
latter case we need to have a full Octave binding not to waste what we
package.
