For technical reasons, transparent viewports cannot support
screen-space reflections, subsurface scattering and depth of field.
Previously, enabling any of these would turn transparent viewports
invisible.
- Harmonise the camera override 2D and 3D APIs
- Switch to using Camera2D/3D nodes to provide override functionality. This makes for simpler code, gets rid of much of copy-pasted camera code and makes code that relies on current viewport camera such as VisibleOnScreenNotifiers and object picking work out of the box.
- Make camera override code only accesible within DEBUG_ENABLED builds
- Add tooltips to some debug draw modes, including when it's unsupported
due to the current rendering method in use.
- Improve documentation related to debug draw modes.
This prevents the antialiasing feather from becoming too wide
at viewport sizes higher than the default, which can lead to blurry visuals.
This is adjusted to account for the 2D scale factor returned on the root
Window, so it takes both the `canvas_items` scaling and
`content_scale_factor` into account.
`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.

Document default behavior when no audio listeners are active
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.
Adds 3D fixed timestep interpolation to the rendering server.
This does not yet include support for multimeshes or particles.
