The fix in 0899a2a8 ensured that when you switched geometry, all other
elements (sharing the same type or representation) would also switch
alongside it. However it would lead to mesh invalidation which broke
some assumptions in the style code. The style code also repeated a lot
of the logic of switch representation (i.e. finding shared
representations) so this seems simpler.
In general the whole representation part of the code is messy and
hopefully over time it'll get better.
The same issue of handling relative paths, doing as_posix, checking
drives, etc was solved again and again in slightly different ways. This
centralises it.
Previously cache_dir was located under site-packages, which is managed
by blender and could be read-only. Now location defaults to eg.
~/.cache/bonsai or equivalent location on other platforms. See #5564
Note this adds a dependency on the platformdirs python module
When loading an ifc project it will search it for bsdd ifcclassifications and will set one as active if finds it, so now it will be a bit more convenient working with bsdd classification assignment as it active bsdd previously was always getting reset when you reload ifc file.

It wasn't working anymore after 27a2c94. Importing IFC file as just geometry should be a separate option from 'should_start_fresh_session' and I've added it as 'import_without_ifc_data' property during project load (now both options are also available for users in project load dialog - https://i.imgur.com/Fvbv4Dy.png)
Kind of experimental. The idea is that it will reassign class e.g. from IfcWindow to IfcWindowType (or vice versa) and will keep the IFC representations and property sets.

It was failing on Windows with something like "ValueError: path is on mount 'L:', start on mount 'C:'".
I guess it doesn't really occur in bonsai as sheets are typically stored next to the titleblocks (we used to use absolute paths awhile ago and now everything is relative to the ifc project)
Previously it would fail with:
PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'bonsai\\bim\\data\\cache\\988c190483ae6bab7cf6b00cee78694d.h5'
Noticed that added drawing camera was linked to the scene collection and after collector.assign it was linked to the 2 collections instead of just 1 - it's own drawing collection and the scene collection.
