Details:

confusion came up on the help list about proper input format for drawPolygon.
After poking around a bit myself I took the liberty of expanding the help a
bit. Will attach the changeset after generating a bug number.

A few notes: the (PX, PY) format only works for column vector inputs, and
produces unexpected results for row vectors (no error or warning).  Is this as
it should be? help text I added specifies they should be column vectors to
match this behavior.

Eg.,

figure(1);
drawPolygon([-1 0 1],[-2 2 -2]);

figure(2);
drawPolygon([-1 0 1]',[-2 2 -2]');


produce very different inputs. Former produces [1 -2; 2 2; 3 -2], latter
produces [-1 -2; 0 2; -2 1] as expected.

Also, there are a few places where warning and error messages still say
Matgeom.  should that now say geometry?
