When the mouse is hovering an embedded window, it is still considered
within the main viewport.
Previously in this case physics picking was executed, as if no embedded
window was there.
This PR introduces an additional check to exclude these cases.
The functionality of the parameter is not limited to drag-and-drop
operations, but it has also other uses.
So its name should not be tied to drag-and-drop.
The API was created in the not yet released Godot 4.4-dev6, so this
change should not be considered compatibility breaking.
`Viewport.get_stretch_transform()` returns the automatically computed
2D stretch transform. Combined with `Transform2D.get_scale()`, this is
useful when using the `canvas_items` stretch mode in a project.
There are many situations where knowing this factor is useful:
- Divide Camera2D zoom to keep the size of the 2D game world identical
regardless of the 2D scale factor (so that UI elements can still be scaled).
- Make certain controls always drawn at 1:1 scale
(e.g. for the crosshair in a FPS). This is done by dividing the Control
node's scale by the scale factor.
With the drag-and-drop rewrite, `SubViewportContainer` nodes were no
longer available as drop-locations.
This PR introduces a configuration option, that allows
`SubViewportContainer` to be considered as drop-location, but disables the
`Control` nodes inside its `SubViewport` children as drop-location.

Document default behavior when no audio listeners are active
- To emit `pressed`, buttons require that the press was initiated while hovering.
- Controls can't grab focus from a mouse click if they're not hovered.
- Hovers are updated both before and after a handled mouse button event.
Make Drag and Drop an application-wide operation.
This allows do drop on Controls in other Viewports/Windows.
In order to achieve this, `Viewport::_update_mouse_over` is adjusted to
remember the Control, that the mouse is over (possibly within nested
viewports). This Control is used as a basis for the Drop-operation, which
replaces the previous algorithm, which was only aware of the topmost
Viewport.
Also now all nodes in the SceneTree are notified about the Drag and Drop
operation, with the exception of SubViewports that are not children of
SubViewportContainers.
InputEventMouseMotion isn't guaranteed to fire only on actual mouse
movement. It's not uncommon for the underlying OS motion event to be
sent either by the OS itself or another application even though the
mouse hasn't moved. Godot will generate such zero-motion
InputEventMouseMotion events itself for things like cursor shape
changes.
Once started, the tooltip timer is reset only after a mouse movement of
at least 5 pixels in one frame.
Adds 3D fixed timestep interpolation to the rendering server.
This does not yet include support for multimeshes or particles.
