`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.

Introduces support for FSR2 as a new upscaler option available from the project settings. Also introduces an specific render list for surfaces that require motion and the ability to derive motion vectors from depth buffer and camera motion.
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.
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`).
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.
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.
When changing `viewport_path`, the `proxy`'s target is changed to a new placeholder.
Add a flag `vp_changed` to prevent calling `setup_local_to_scene` (mainly called by toggling `resource_local_to_scene`) when the target viewport has not changed.
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.
When a Viewport is not directly attached to the screen, the
function `Viewport::get_mouse_position` can't rely on
`get_screen_transform`, because that function is ambiguous in
these situations.
In these cases it is necessary to use the mouse position from
the most recent mouse IputEvent.
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.
The associated `ViewportTexture`s will update the `viewport_path`
in time when the `Viewport`'s nodepath is changed (caused by renaming
the node names or moving in the SceneTree dock).
If the target `Viewport` is changed by resetting the `viewport_path`,
the `ViewportTexture`s will be re-setup and emit `changed` signal in
time.
* 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.
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`.
This patch adds a viewport-configuration-option for sorting
physics-picking events by the Z-Index and the scene tree position
of the collision objects.
`Viewport.to_screen_rect` is used only in a single location to compare it
to `Rect2i()`.
When called from `SubViewport`, `to_screen_rect` is always equal to `Rect2i()`.
When called from `Window`, `to_screen_rect` is always different from `Rect2i()`.
So the comparison `to_screen_rect != Rect2i()` can be replaced by
`Object::cast_to<Window>(this)`.
This allows the removal of `Viewport.to_screen_rect` and the simplification of
`Viewport::_set_size`.
CanvasItem::get_screen_transform returns a transform from the CanvasItem
to the coordinate system, where a Popup - created as a child of the
CanvasItem - should be opened.
get_screen_transform makes some simplifications, that work well, when used
in the editor, but not in general cases.
Since Popups like Tooltips are now used more commonly in projects,
it becomes necessary to correct these simplifications.
This solution introduces Viewport::get_popup_base_transform, which makes
the necessary calculations.
