This function returns UU and VV, the coordinates for orthogonal mapping.
The projection is performed as if the texture was placed with point O
representing (UU,VV) = (0,0) and UU running along X and VV running along Y.
The map is then projected parallel to itself onto the surface.

This is the point on surface to be projected.  The default is P.

This point represents the origin of the plane.
This must be a point. The default is point(0,0,0).

This point represents the Xaxis of the plane.
This must be a point. The default is point(1,0,0).

This point represents the Yaxis of the plane.
This must be a point. The default is point(0,1,0).

This a return value, the "horizontal" mapping coordinate.
The projection is performed as if the texture was placed with point O
representing (UU,VV) = (0,0) and UU running along X and VV running along Y.
The map is then projected parallel to itself onto the surface.

This a return value, the "vertical" mapping coordinate.
The projection is performed as if the texture was placed with point O
representing (UU,VV) = (0,0) and UU running along X and VV running along Y.
The map is then projected parallel to itself onto the surface.
