Created: 25-Jan-2006 Alexandre A. Del Savio Criada a restrição de superfície.

Modified: 10-Fev-2006 Alexandre A. Del Savio Na função ConstSurfaceBuild passou-se a criar a superfície PFS (Parametrized Faceted Surface).

Modified: 13-Apr-2006 Alexandre A. Del Savio Modificada a funcões SurfaceToLocal, ConstSurfaceLocal, SurfaceToGlobal, SurfaceToGlobalParametric, ConstSurfaceGlobalParametric, ConstSurfaceGlobal, que passam a retornar 0 ou 1 em caso de falha ou sucesso respectivamente.

Modified: 21-Jun-06 Alexandre A. Del Savio Modified the ConstSurfaceNew function when it was removed the first parameter "int i" and it started to use the ContNumConstrainRead variable.
