Fixes#64988.
Fixes#64997.
This caused several regressions (#64988, #64997,
https://github.com/godotengine/godot/issues/64997#issuecomment-1229970605)
which point at a flaw in the current logic:
- `Control::NOTIFICATION_ENTER_TREE` triggers a *deferred* notification with
`NOTIFCATION_THEME_CHANGED` as introduced in #62845.
- Some classes use their `THEME_CHANGED` to cache theme items in
member variables (e.g. `style_normal`, etc.), and use those member
variables in `ENTER_TREE`, `READY`, `DRAW`, etc. Since the `THEME_CHANGE`
notification is now deferred, they end up accessing invalid state and this
can lead to not applying theme properly (e.g. for EditorHelp) or crashing
(e.g. for EditorLog or CodeEdit).
So we need to go back to the drawing board and see if `THEME_CHANGED` can be
called earlier so that the previous logic still works?
Or can we refactor all engine code to make sure that:
- `ENTER_TREE` and similar do not depend on theme properties cached in member
variables.
- Or `THEME_CHANGE` does trigger a general UI update to make sure that any
bad theme handling in `ENTER_TREE` and co. gets fixed when `THEME_CHANGE`
does arrive for the first time. But that means having a temporary invalid
(and possibly still crashing) state, and doing some computations twice
which might be heavy (e.g. `EditorHelp::_update_doc()`).
Adds a new, cleaned up, HashMap implementation.
* Uses Robin Hood Hashing (https://en.wikipedia.org/wiki/Hash_table#Robin_Hood_hashing).
* Keeps elements in a double linked list for simpler, ordered, iteration.
* Allows keeping iterators for later use in removal (Unlike Map<>, it does not do much
for performance vs keeping the key, but helps replace old code).
* Uses a more modern C++ iterator API, deprecates the old one.
* Supports custom allocator (in case there is a wish to use a paged one).
This class aims to unify all the associative template usage and replace it by this one:
* Map<> (whereas key order does not matter, which is 99% of cases)
* HashMap<>
* OrderedHashMap<>
* OAHashMap<>
These typedefs don't save much typing compared to the full `Ref<Resource>`
and `Ref<RefCounted>`, yet they sometimes introduce confusion among
new contributors.
This reverts commit a988fad9a0.
As discussed in #57725 and clarified in #57788, `SNAME` is not meant to be used
everywhere but only in critical code paths. For theme methods specifically, it
was by design that only getters use `SNAME` and not setters.
