Namely, move the drive dropdown to just the left of the path text box and don't include the former
in the latter.
This improves the UX on Windows.
In the UNIX case, since its concept of drives is (ab)used to provide shortcuts to useful paths, its
dropdown is kept at the original location.
EditorData::undo_redo.add_do_property and EditorData::undo_redo.add_undo_property is used in EditorData::paste_object_params to implement this feature. It's action name is set to "Paste Params"
Changes made
* Removed the call for clearing the history on paste params case.
* Instead of directly setting the properties value, EditorData::undo_redo is used.
Those were problematic as they call a method of their parent class,
but callable_mp does not allow that unless it's public.
To solve it, we declare a local class that calls the parent class'
method, which now needs to be protected to be accessible in the
derived class.
It's tedious work...
Some can't be ported as they depend on private or protected methods
of different classes, which is not supported by callable_mp (even if
it's a class inherited by the current one).
Remove now unnecessary bindings of signal callbacks in the public API.
There might be some false positives that need rebinding if they were
meant to be public.
No regular expressions were harmed in the making of this commit.
(Nah, just kidding.)
Main:
- It's now implemented thanks to `<mutex>`. No more platform-specific implementations.
- `BinaryMutex` (non-recursive) is added, as an alternative for special cases.
- Doesn't need allocation/deallocation anymore. It can live in the stack and be part of other classes.
- Because of that, it's methods are now `const` and the inner mutex is `mutable` so it can be easily used in `const` contexts.
- A no-op implementation is provided if `NO_THREADS` is defined. No more need to add `#ifdef NO_THREADS` just for this.
- `MutexLock` now takes a reference. At this point the cases of null `Mutex`es are rare. If you ever need that, just don't use `MutexLock`.
- Thread-safe utilities are therefore simpler now.
Misc.:
- `ScopedMutexLock` is dropped and replaced by `MutexLock`, because they were pretty much the same.
- Every case of lock, do-something, unlock is replaced by `MutexLock` (complex cases where it's not straightfoward are kept as as explicit lock and unlock).
- `ShaderRD` contained an `std::mutex`, which has been replaced by `Mutex`.
