Unparented popups can easily get lost in backround, but they still block top level event loop when run with ::exec() thus preventing interactions with main window. This mainly happens on wayland. Setting the parent ensures they are always kept on top and reasonably positioned.
Every basic data type is stored in Base module, color is standing out as
one that does not. Moving it to Base opens possibilities to integrate it
better with the rest of FreeCAD.

- if pvtu file filtering is on, there is by design not on every call of WriteColorData() data
(on other occasions of GetArray(array) the result is checked, for two calls is was forgotten)
- also some automatic code formatting according to our current clang file
- it is sensible to filter by default, however, it turned out that on some complex models Elmer fails to compute if the mesh volume regions are too small (in most cases) or at a certain mesh region. By disabling the filtering, one gets at least for the latter case a visual feedback where the mesh volume of the different CPU are (by also setting a transparency to the result pipeline).
- To speed up analyses one calculates on several CPU cores. The result is a partial VTU file.
Unfortunately when applying a transparency the boundaries of the volumes computed by each CPU core are always visible. This makes it often unusable for visualizations.
The solution is to filter the results the same way a clip filter does.
- for harmonically driven forces, the results of course also have an imaginary part. Elmer outputs the real and the imaginary parts as separate result field. However, for several applications one needs the absolute (sqrt(Re^2+Im^2)
- therefore offer also absolute field if there are real/imaginary results
- for the case that pipeline with a field is active, then another pipeline that does not display any field, we cannot just return because the pipeline cannot have the color bar range of the prevision pipeline
