/*
    Purpose: Returns a tessellation (also called a triangulation) of each 
             surface of the specified part. For parts, acts on all surfaces. 
             For assemblies, acts only on surfaces of the assembly, not

             <p> NOTE: Use function ProPartTessellationFree() to release memory 
             allocated by this function.

    Input Arguments:
        part - The part
        chord_ht - The maximum allowable chord height ( > 0 )
        angle_cntrl - The angle control (between 0.0 and 1.0)
        include_quilts - Include quilts and facets or not

    Output Arguments:
        output - Pointer to a ProArray of ProSurfaceTessellationData, one for 
                 each surface of the part.

    Return Values:

        PRO_TK_BAD_INPUTS - One or more of the input arguments were invalid.
        PRO_TK_GENERAL_ERROR - A tessellation error occurred.

                  been assigned a material, this is the density for the 
                  material.
