function drawPartialPatch(u, v, z, varargin)
%DRAWPARTIALPATCH Draw surface patch, with 2 parametrized surfaces.
%
% usage:
% drawSurfPatch(u, v, zuv)
% where u, v, and zuv are three matrices the same size, u and
% corresponding to each parameter, and zuv being equal to a function of u
% and v.
%
% drawSurfPatch(u, v, zuv, p0)
% If p0 is specified, two lines with u(p0(1)) and v(p0(2)) are drawn on
% the surface
