The original implementation of the surface() function used a simple
B-spline representation for the surface, which generated degenerate
surface with several of OpenSCAD's demo input files. This commit
modifies the algorithm to generate a discrete surface identical to the
one generated within OpenSCAD itself. It also adds several units tests
to identify future regressions.
Note that PNG input is not yet supported for the surface() function.
The OpenSCAD module did not have any unit tests. This commit adds the
basic framework (and two very simple tests). The framework is modeled
after the unit tests in the FEM module.
In CMake 3.0 the policy CMP0050 was introduced where it could be set to OLD to keep this behaviour while for NEW an error was raised.
Since CMake 3.5.2 a warning comes up when using the OLD behaviour and that it will be removed in a future version.
In FreeCAD we switched to the new behaviour now and removed the SOURCE signature from add_custom_command which affects the macros
fc_copy_sources, fc_target_copy_resource and fc_target_copy_resource_flat and their usage.
It's not possible any more to add files to a target by using the macros. Now a file must be added to the target before using the macros.
