Not that this is critical, but it makes behavior of GUI and 2D/3D picking consistent among them.
This also contributes to dropping GUI focus when the mouse leaves the window (in addition to when it loses focus).
1. Consider 'own_world' as well as 'world' to stop propagating enter/exit world notifications.
2. Clean & fix handling of camera currency.
This fixes some random crashes and error logs in the editor; namely
- when enabling/disabling own world in a Viewport;
- when switching back from a subscene displayed into a main scene's Viewport;
- when exiting the editor after any of them;
- memory corruption (can that explain certain other seemingly unrelated crash reports?).
This also fixes situations where a Viewport and its main Camera get out of sync about which World is relevant to them.
Acknowledge mouse button events as position tellers (to make picking more solid; for instance, the touch mouse is raised with a mouse unpressed event that may have a more current position)
Forget mouse position for physics if touch mouse raised (because the position known as last is no longer meaningful)
Remove needless check for mouse over/exit (now there's code to inject an spurious move for cases where camera/objects have moved)
Restrict 2D mouse over/exit to mouse events (including emulated from touch; true touches shouldn't trigger the signals)
Fixes#26460.
WARNING: Test well in every OS, if mouse wheel events are not properly sent as pressed+unpressed pair, it will fail and break (and the OS needs to be fixed). Only tested on X11 so far.
At least the ones I got when I compiled it using Mingw64 POSIX on Xubuntu 18.04. Plus use the Size2 of get_window_size() directly, rather than reconstructing it.

Some of those are bugs and need further work, they are identified with
`// FIXME` comments.
This allows more consistency in the manner we include core headers,
where previously there would be a mix of absolute, relative and
include path-dependent includes.
New APIs in 2D physics allow intersection queries filtered by CanvasLayer object instance id. Viewport keep an inventory of its descendant CanvasLayers and takes advantage of all that to test picking with the mouse/touch position correctly transformed for each CanvasLayer.
It seems that popups were intended to "grab" the mouse click that triggered them, but their intent was being lost. This commit does the necessary changes to let it happen and updates items that were trying to get advantage of it, because the semantics of `Control::grab_click_focus()` have changed a bit. Namely, it must be called **before** showing the modal.
This allows to popup a menu and activate an item in it in a single click-point-release cycle, instead of having to click once to open the menu and once more to pick an item.
This ability is extended even to context menus activated with the RMB (or any other mouse button, for that matter). The editor benefits from this in the context menu of the tree dock, which has been patched to opt-in for this feature.
This improves UX a bit by saving unnecessary clicks.
From now on, `PopupMenu` always grabs the click and also invalidates the first button release unless the mouse has moved (that's what `set_invalidate_click_until_motion()` was doing and now it's removed), so there is no longer the need of doing both things at every point a pop-up menu is shown.
Previously this option seemed to be the sole responsible for enabling
physics processing in Viewport, while several other features like
tooltips and debugging collision hints rely on it.
All this logic is moved to internal processing (it's incorrect to let
it be affected by users disabling physics/idle processing), and disabling
physics object picking no longer affects the internal physics processing.
Fixes#17001.
Notable potentially breaking changes:
- PROPERTY_USAGE_NOEDITOR is now PROPERTY_USAGE_STORAGE | PROPERTY_USAGE_NETWORK, without PROPERTY_USAGE_INTERNAL
- Some properties were renamed, and sometimes even shadowed by new ones
- New getter methods (some virtual) were added
Using `misc/scripts/fix_headers.py` on all Godot files.
Some missing header guards were added, and the header inclusion order
was fixed in the Bullet module.
