- modified the Properties Tab for various FlatCAM objects preparing the move of Properties Tool data into the Properties Tab
- if the Properties tab is in focus (selected) when a new object is created then it is automatically selected therefore it's properties will be populated
- added a bilinear interpolation calculation class from: https://github.com/pmav99/interpolation
- in CNCJob UI Autolevelling: made sure that the grid can't have less than 2 rows and 2 columns when using the bilinear interpolation or 1 row and 1 column when using the Voronoi polygons
- in CNCJob UI Autolevelling : in manual mode, Points can be chosen only when clicking inside the object to be probed
- in CNCJob UI Autolevelling: made sure that plotting a Voronoi polygon is done only for non-None polygons
- in CNCJob UI Autolevelling: remade the probing points generation so they could allow bilinear interpolation
- in Properties Tool, for CNCJob objects made out of Excellon objects, added the information's from Tool Data
- in Properties Tool made sure that the set color for the Tree parents depends on the fact if the gray icons set are used (dark theme) or not
- Properties Tool - properties for a Gerber objects has the Tool Data now at the end of the information's
- in CNCJob UI Autolevelling - Voronoi polygons are now plotted
- in CNCJob UI Autolevelling - adding manual probe points now show some geometry (circles) for the added points until the adding is finished
- in CNCJob UI Autolevelling - added a save dialog for the probing GCode
- added a new GUI element, a DoubleSlider
- in CNCJob UI Autolevelling - GRBL controller - Control: trying to add DoubleSlider + DoubleSpinner combo controls
- in CNCJob UI Autolevelling - added a mini gcode sender for the GRBL to be able to send the probing GCode and get the height map (I may make a small and light app for that so it does not need to have FlatCAM on the GCode sender PC)
- in CNCJob UI Autolevelling finished the probing GCode generation for MACH/LinuxCNC controllers; this GCode can also be viewed
- cleanup of the CNCJob UI; added a checkbox to signal if any append/prepend gcode was set in Preferences (unchecking it will override and disable the usage of the append/prepend GCode)
- the start Gcode is now stored in the CNCJob object attribute gc_start
- GCode Editor - finished adding the ability to select a row in the Tools table and select the related GCode
- by default now a new blank Geometry object created by FlatCAM is of type multigeo
- made sure that optimizations of lines when importing SVG or DXF as lines will not encounter polygons but only LinesStrings or LinearRings, otherwise having crashes
- fixed the import SVG and import DXF, when importing as Geometry to be imported as multigeo tool
- fixed the import SVG and import DXF, the source files will be saved as loaded into the source_file attribute of the resulting object (be it Geometry or Gerber)
