-Added a new method in Resource: reset_state , used for reloading the same resource from disk
-Added a new cache mode "replace" in ResourceLoader, which reuses existing loaded sub-resources but resets their data from disk (or replaces them if they chaged type)
-Because the correct sub-resource paths are always loaded now, this fixes bugs with subresource folding or subresource ordering when saving.
According to the docs at
https://docs.godotengine.org/en/stable/tutorials/plugins/editor/import_plugins.html#the-editorimportplugin-class
> The get_visible_name() method is responsible for returning the name of
> the type it imports and it will be shown to the user in the Import dock.
> You should choose this name as a continuation to "Import as", e.g.
> "Import as Silly Material"
I've verified Godot's behavior reflects this, so the code examples
should reflect this.
Also document propagating save error in EditorImportPlugin.
It seems that the suggested code ignores any error from
`ResourceSaver.save`, but I think we should return it.
-For inspector refresh, the inspector now detects if a property change by polling a few times per second and then does update the control if so. This process is very cheap.
-For property list refresh, a new signal (property_list_changed) was added to Object. _change_notify() is replaced by notify_property_list_changed()
-Changed all objects using the old method to the signal, or just deleted the calls to _change_notify(<property>) since they are unnecesary now.
Cylinder collision detection uses a mix of SAT and GJKEPA.
GJKEPA is used to find the best separation axis in cases where finding
it analytically is too complex.
Changes in SAT solver:
Added support for generating separation axes for cylinder shape.
Added support for generating contact points with circle feature.
Changes in GJKEPA solver:
Updated from latest Bullet version which includes EPA fixes in some
scenarios.
Setting a lower EPA_ACCURACY to fix accuracy problems with cylinder vs.
cylinder in some cases.
-Rendering server now uses a split RID allocate/initialize internally, this allows generating RIDs immediately but initialization to happen later on the proper thread (as rendering APIs generally requiere to call on the right thread).
-RenderingServerWrapMT is no more, multithreading is done in RenderingServerDefault.
-Some functions like texture or mesh creation, when renderer supports it, can register and return immediately (so no waiting for server API to flush, and saving staging and command buffer memory).
-3D physics server changed to be made multithread friendly.
-Added PhysicsServer3DWrapMT to use 3D physics server from multiple threads.
-Disablet Bullet (too much effort to make multithread friendly, this needs to be fixed eventually).
This change allows collide_shape, intersect_shape, cast_motion and
rest_info in both 2D and 3D to ignore disabled shapes and make them
consistent with the physics simulation.
In some other cases, _cull_aabb_for_body is used and filters shapes out
internally, but whenever a physics query uses the broadphase directly
without calling _cull_aabb_for_body, disabled shapes can be returned
and need to be filtered out.
Setting each point's position was missing for 3D. Now enabling collision
render debug will display contact points for 3D physics, the same way it
does for 2D physics.
Note: Multimesh rendering seems not to work in this scenario on master,
but it's working fine on 3.2.
