- fixed a number of issues, mostly leftovers from moving the UI of a Plugin in its own class
- fixed some bugs in the Punch Gerber plugin
- fixed some bugs where the 'pool' parameter was not passed when creating shapes collections (in 3D graphic mode); I wonder how it worked until now
- added a new feature in the Isolation Plugin: now for all the isolation Geometry objects this plugin can do a supplementary simplification of the geometry using the tolerance parameter defined in the General Parameters. This should lead to a reduced number of tool lifts when doing corners
- remade the Film Plugin such that the `skew` feature is now done in length units as opposed with the previous usage of angles
- refactored some big methods from the Film Plugin
- some more code is refactored in the Preferences
- the axis will now be drawn on the canvas as they were left in the previous run (just like the HUD and the Workspace)
- for processors with less than 4 cores now the default number of workers is 1 (changed from 2)
- some graphical settings go now directly to the defaults dictionary and will not pass through the `options` app dictionary
- fixed some outstanding issues from the PyQt6 port
- PEP8 fixes
- minor fixes
- updated the saving of Preferences to update the self.options too: the `Apply` action will update the self.options but the `Save` action will save the updated preferences to the file on disk
- added ability to turn off the outline plotting for Gerber objects (will speed up the plotting but the plotting visual quality will degrade); controlled from Preferences -> Gerber -> General
- plotting visuals in 3d graphic mode will no longer create some unnecessary lists
- applied the FCMessageBox GUI elements everywhere; there is still a hack in appTranslation file where I needed to re-implement the class due of some circular imports errors
- in 2Sided Plugin: duplicated set of coordinates in Alignment Drills are removed
- in 2Sided Plugin: Shift+LMB will add automatically the clicked coordinates in the Alignment Drills location
- in 2Sided Plugin added a new typ of alignment drills: manual. This mode will no longer add pairs of drill holes mirrored against reference but only add in place drill holes
- In Paint Plugin fixed the Area select mode to work with Geometry object created by the Geometry Editor
- in Paint Plugin some changes in the way the source object is autoloaded
- in Paint, NCC and Cutout Plugins when using a mode that require to be terminated (by mouse RMB or ESC key) the notebook UI element is disabled until this is done
- the Aperture Table in the Gerber Editor is no longer extended to show all apertures at once
- in Preferences: Excellon, Geometry and CNCJob tabs, updated the UI to the new design
- in Excellon Editor made sure that the tool diameter is always updated before adding a new drill (or drill array)
- changing units is not possible while in Editors
- changing units outside the Preferences will make no permanent changes
- deleting all shapes from the shapes collection (OpenGl graphics) will reset also the index in the collection data dict
