Details:

This patch adds the functionality to calculate vertexnormals for patch
objects.

While it seems to work quite good in most cases, I do not know how to immitate
Matlab's behavior in the following case (a test is included):
In Matlab:

>> hpa = patch ();
>> get (hpa, 'VertexNormals')
ans =
     0     0     1
     0     0     1
     0     0     1
>> get (0, 'DefaultPatchVertexNormals')
ans =
     []


The vertexnormals should be calculated while the patch is created. I managed
to get that behavior after calling "reset (hpa)". But I do not know where to
call update_normals to trigger it when the patch is created with default
values.

I would appreciate any help, tips, info and opinions.
