Construct a simple patch:

nu
Number of columns
nv
Number of rows
uwrap
Whether the patch is connected between the last and first columns.
vwrap
Whether the patch is connected between the last and first rows.
vertex
Attribute data per vertex (nu * nv elements)
uniform
Uniform values for patch faces. The number of entries should be:
- Linear: (nu + uwrapped - 1) * (nv + vwrapped - 1)
