3de9afc4a9 Fix crash when hiding a Control during mouse-entering
gui.mouse_over can be set to `nullptr` in the `NOTIFICATION_MOUSE_ENTER`-
user-callback a few lines above. This case was previously not handled.

d24d73ba31 Make mouse-enter/exit notifications match mouse event propagation
`NOTIFICATION_MOUSE_ENTER` and `NOTIFICATION_MOUSE_EXIT` now includes
the areas of children control nodes if the mouse filters allow it.

In order to check if a Control node itself was entered/exited, the newly
introduced `NOTIFICATION_MOUSE_ENTER_SELF` and
`NOTIFICATION_MOUSE_EXIT_SELF` can be used.

Add a Disable 2D property to Viewport
This is the 2D counterpart to the existing Disable 3D property.
Its functionality is already internally implemented and used,
but it wasn't exposed.

fe000277ea Bind remaining theme properties to their respective classes
This adds binds for GraphEdit/GraphElement/GraphNode, which were
skipped before due to a rework. This also adds binds for Window,
which was skipped before due to a complicated code organization.

Also adds theme cache entries/direct cache access to a few places
that previously missed it. Some theme properties are now exposed
to other classes via friendships or public getters for convenience.

This removes all string-based theme access from scene/ classes.

59c13fea5d Fix nodes receiving mouse events in black bars of Window
Previously for InputEvents there was no distinction between
Window-area and Viewport-area.
This was problematic in cases where stretching was used and the Window
contained black bars at the sides of the Viewport.
This PR separates the area of Window and Viewport regarding InputEvents.

4795c3cdfa Clear the previously set state when configuring for a new scene root node
Saving a subscene causes the main scene to be re-instantiated. And the resource
instance in the main scene will be reused when the main scene is re-instantiated.
So for resources with `resource_local_to_scene` enabled, resetting state may be
necessary (at least for `ViewportTexture`).

57eb762bae Add option to enable HDR rendering in 2D
This is needed to allow 2D to fully make use of 3D effects (e.g. glow), and can be used to substantially improve quality of 2D rendering at the cost of performance

Additionally, the 2D rendering pipeline is done in linear space (we skip linear_to_srgb conversion in 3D tonemapping) so the entire Viewport can be kept linear.
This is necessary for proper HDR screen support in the future.

1c3c17c608 Refactor mouse_entered and mouse_exited notifications
The previous implementation for signals mouse_entered and mouse_exited
had shortcomings that relate to focused windows and pressed mouse buttons.
For example a Control can be hovered by mouse, even if it is occluded by
an embedded window.

This patch changes the behavior, so that Control and Viewport send
their mouse-enter/exit-notifications based solely on mouse position,
visible area, and input restrictions and not on which window has
focus or which mouse buttons are pressed. This implicitly also
changes when the mouse_entered and mouse_exited signals are sent.

This functionality can not be implemented as a part of
Viewport::_gui_input_event, because of its interplay with Windows and
because Viewport::_gui_input_event is based on input and not on
visibility.

e6386bc843 Make SubViewportContainer event propagation aware of focused Control
Propagate `InputEvents` without position either
- during the Input-stage, when it has focus or
- during the Unhandled-Input-stage, otherwise

This makes sure that Gui-Input happens in the correct order.

Move "Unhandled key Input" handling before "Unhandled Input" handling,
so that Unicode input with Alt / Ctrl modifiers are sent to the nodes
in the correct order.

Change the default focus mode of `SubViewportContainer` from
`FOCUS_NONE` to `FOCUS_CLICK`, to automatically remove focus from
other `Control`-nodes, when clicking inside a `SubViewport`.

543fdc1490 Fix passive mouse hovering for physics
Currently mouse hovering doesn't update the state, when collision objects
or the camera move.
This PR fixes this problem by taking the mouse position from the viewport
and not from a nonexistent previous event.

Since previous events could potentially be a long time ago, their
modifier-key state might be outdated. This PR fetches the current
status of modifier-keys from `Input`.

These changes allow the removal of some class-variables and making
additional simplifications.

In these cases it is necessary to use the mouse position from

6d490ce8de Deprecate push_unhandled_input
The functionality of `push_unhandled_input` has changed so that it no
longer propagates input events to SubViewports.
This makes it less predictable and it should be deprecated in favor of
`push_input` which provides the same functionality and more.

Also this deprecation simplifies the Viewport-API by reducing the methods
for pushing input events, so that users don't need to worry about when
to use which function in order to insert input events.

a9bf3de08e Fix InputEvent being used twice
A single mouse click can cause multiple actions, which contradicts
the paradigm that a single Input Event should cause only a single
action.

The solution consists of two parts:
1. Physics Picking as the last step during viewport input event
handling, currently doesn't set the event as handled. This PR sets
the event as handled in the case of physics picking.
2. After an InputEvent is processed by a SubVieportContainer, it is
sent to its parent, even if it set as handled within the SubViewport.
This PR adds an additional test to check if the event is handled
before propagating the event to the parent Control.

The associated `ViewportTexture`s will update the `viewport_path`

If the target `Viewport` is changed by resetting the `viewport_path`,
the `ViewportTexture`s will be re-setup and emit `changed` signal in
time.

104392ef4e Remove NOTIFICATION_MOVED_IN_PARENT
* This notification makes node children management very inefficient.
* Replaced by a NOTIFICATION_CHILDREN_CHANGED (and children_changed signal).
* Changed Canvas code (and similar) to use the above signal, to perform more efficiently.

This PR breaks compatibility (although this notification was very rarely used, even within the engine), but provides an alternate way to do the same.
It is required for the changes in #75627 to be entirely effective.

Apply clamp_to_embedder on parent resize and popup.
Fixes #75084.

The clamp_to_embedder setting was added in 8be16e0704,
but was not set on any of the in-editor dialogs.

This patch sets `clamp_to_embedder` on editor dialogs so they cannot be dragged out of the frame.
This also modifies `clamp_to_embedder` so a window is clamped to the bounds of an embedder when
it pops up and when the parent is resized.

8836f2160a Move call of push_unhandled_input from Window to Viewport
This solves the problem, that mouse events get sent to SubViewports
even if they are outside of the visible area of the SubViewport.

This changes makes SubViewportContainer::unhandled_input redundand.
Shortcut Events now need to be distributed via push_input, in order for
them to be able to reach SubViewports.

34a7fc7447 Fix some ways to create inconsistent Viewport sizes
In the editor, it was possible to set the size of a `SubViewport` even
in cases where a parent `SubViewportContainer` had stretch enabled.

This PR disables editing a `SubViewport.size` while the parent disallows
it and it makes necessary adjustments during `NOTIFICATION_ENTER_TREE`.
