Fix of #5007 - "Reload from disk" causes objects converted to inches to revert to mm
1) Storing and reloading the "source_in_inches" source flag from AMF and 3MF
2) When converting objects with mixed "inches" volumes, do the right thing
and do not convert those that do not need conversion.
to help with detecting "not changed" event when taking
Undo/Redo snapshot or synchronizing with the back-end.
Converted layer height profile and supports / seam painted areas
to the same timestamp controlled structure.
1) All slicer's exceptions are now derived from Slic3r::Exception.
2) New exceptions are defined for slicing errors.
3) Exceptions are propagated to the Plater to show.
It remains to modify the slicing back-end to throw the new SlicingError
exceptions instead of std::runtime_error and to show the other exceptions
by a message dialog instead of a notification.
Drain holes reference position was saved slightly above the mesh to avoid problem when the hole is placed on flat or nearly flat surface
The depth of the hole was internally bigger than what the user has set to compensato for it
However, this leads to problem with scaling and makes reprojection of the holes on the mesh complicated
This commit changes the reference point to the point on the mesh and the extra elevation is handled when rendering and drilling the hole.
The change is reflected in 3MF drain holes versioning so that old 3MFs are loaded correctly.
Reprojection on the mesh after reload from disk/fix through netfabb has been enabled.
into the 3MF / AMF.
Improved accuracy of ModelVolume's mesh transform back from Object's
coordinate space to its own coordinate space after reloading
from 3MF / AMF.
Fixed layouts after the second opening of the dialog.
(Removing any extruder from the sequence does not cause an incorrect layout)
Validation of entered values added
(0 is not a valid value)
1) Reworked void Plater::priv::reload_from_disk() to be more general
2) Added source data to class ModelVolume
3) Modified .3mf import/export to save/load volume matrices and source data
4) Incremented .3mf version to 2
