Now we do not rely on small offset to keep using inner curves to create linings, if some part of the lining is not present (which happens on mullions and transoms) we'll create U or L shape extrusion instead of rectangle with inner curve.
Long story short - this should keep ifc for windows valid.

It's a bit hacky since we still use really small offsets to keep "The outer curve shall enclose all inner curves." rule for IfcArbitraryProfileDefWithVoids valid.
To test, go into add-on preferences and enable "Should Stream". Then load an IFC-SPF in advanced mode, and disable "Load Geometry" before loading (the geometry iterator doesn't work with streaming).
f attributes holding entity lists are expanded in SQL, this means that you end up with significantly more rows. Also, you cannot have the ifc_id marked as a UNIQUE field / benefit from unique primary key index. So leaving the fields as JSON is actually significantly more efficient (almost 10X faster to load a model into BBIM).
Added new panel. in shader graph N-panel that allows you to create fully GLTF and IFC compatible shader graphs by just tweaking parameters from the panel. Note that it's still saved to IFC only when you hit "Save Current Style", before that it's still just stored in blender.

The premise is that if you want to have non-external style you'd be able to create it entirely from this panel - so there will no need to guess or to remember which parameters from the graph are supported by IFC and which are not.
It's still work in progress, still need to polish it, add support for more reflectance methods and add suport for textures (need to be able to import/export it with .ifc and set them from this panel).
Taking into account that now we have error messages if user will try to remove the last material layer which would make layer set invalid ifc.
FAILED test/bim/test_feature.py::test_remove_material_set_layer - AssertionError: Failed to run operator bpy.ops.bim.remove_layer(layer=IfcStore.get_file().by_id(93).MaterialLayers[...
Some bim test was failing because of it

Duplicated objects were not able to have their own collection after 586707dd2
Also fixed bim test
FAILED test/bim/test_feature.py::test_copy_a_storey - AssertionError: assert 'IfcBuildingStorey/My Storey.001' in ['IfcBuildingStorey/My Storey']
Unlinking was using copied object name for the unlinked object instead of the original one.
So it worked like Cube -> IfcWall/Cube -> Cube.001 and bim test was failing:
FAILED test/bim/test_feature.py::test_unlink_object - AssertionError: The object "Cube" does not exist
1) Explicitly set empty ifc project not to load demo library - was still loading because it was using my default scene which caused errors.
2) typo in dimension check assertion message
Fixed error that was occuring if you try to import .ifc file where spatial element contains only grid and will use advanced mode, filter mode = "IFC Class" and check "Filter Spatial Elements".
Error occured because spatial element was filtered out but then when ifc grid was created and importer to find a spatial element based collection for the grid it couldn't find it.

In ifc2x3 IfcProject is not IfcContext because there is no IfcContext in ifc2x3 and it was causing the error below on .ifc import with filtered spatial elements.
Also added small refactor
