fixes#7008:
- the point data must be read also when the center changed
- when the dialog is called it has only the value for the current field, thus recompute the feature to fill all fields with data
- on clicking on a mesh point display the value at the clicked position
- due to the object's recomputation at the start, a complete recomputation (for the whole pipeline) is needed on closing the dialog
- we cannot assume to have a geometry at position (0, 0, 1) this initialize at (0, 0, 0)
- also don't hardcode the unit in the UI file
- also fix wrong property description
- property "Radius" is not used in the code and it seems it is only there as copy paste bug once the point filter was implemented. However close to a release, keep the property and just mention it is unused.
- in contrary to other filters the properties have no unit handling
(there are several bugs in line filter and to fix them, unit handling is necessary)
- at the moment you cannot get the result data, for example to make your own plot. Also for the line you might want to have unequal x-steps etc. Especially for the data point filter not getting the data actually makes the tool quite useless.
- therefore set the properties to output
fixes#6683
We cannot cast the object type before checking it and in case the object is wrong, the filter cannot be processed and the user needs info about his mistake that he can fix this.
- also some code style fixes by MSVC
- as reported here: https://forum.freecadweb.org/viewtopic.php?p=583133#p583133
The point is that the user cannot know that he has to multiply the shown numbers for displacements by 0.001 but for the displayed stresses by 1e6 while the temperature is already correct.
The fix is to be consistent and display in SI units. This commit does this and was tested using unit systems with mm and meter based length.
- in order to benefit from the previous fix when e.g. setting up a clip filter of a clip filter one needs the set inputs untouched. The existing modes however changed all an the addition of a new filter.
Use this new mode as default since it preserves the inputs as the users set them on the filter creation
Race conditions introduced after using OpenMP in `FemMesh::getNodesByFace` and
`FemMesh::getNodesBySolid` because of which nodes were randomly added or removed
from sets. Solved by replacing `SMDS_MeshNode::X()` etc., which are not thread
safe, with the thread-safe `SMDS_MeshNode::GetXYZ()`.
