This solves #17931 and makes the script editor consistent with other text editors(Sublime, Gedit, Vim) in displaying the position rather than the raw number of characters.
Editing the `Text` property through the editor causes a wrong
placement of the placeholder, as it calls `LineEdit::clear_internal`,
which was wrongly reseting the cached placeholder width.
Fix#18184.
Now generating mouse events from touch is optional (on by default) and it's performed by `InputDefault` instead of having each OS abstraction doing it. (*)
The translation algorithm waits for a touch index to be pressed and tracks it translating its events to mouse events until it is raised, while ignoring other pointers.
Furthermore, to avoid an stuck "touch mouse", since not all platforms may report touches raised when the window is unfocused, it checks if touches are still down by the time it's focused again and if so it resets the state of the emulated mouse.
*: In the case of Windows, since it already provides touch-to-mouse translation by itself, "echo" mouse events are filtered out to have it working like the rest.
On X11 a little hack has been needed to avoid a case of a spurious mouse motion event that is generated during touch interaction.
Plus: Improve/fix tracking of current mouse position.
** Summary of changes to settings: **
- `display/window/handheld/emulate_touchscreen` becomes `input/pointing_devices/emulate_touch_from_mouse`
- New setting: `input/pointing_devices/emulate_mouse_from_touch`
-Missing Icons
-Missing freezing option (for baking light and faster load)
-Missing a way to export from Godot (GLTF2?)
-Probably buggy (may freeze editor, can be worked around easily, but let me know if this happens so it's easier to catch bugs)
Happy testing!
Allows shortening the two line method of Timer.set_wait_time
followed by Timer.start set wait_time as a parameter to
Timer.start. Also modifies the class documentation.
Fixes: #18107
Adds support for CMD+Backspace, to delete all text
before the cursor in the line and CMD+Delete to delete
all text after the cursor in line following the typical
MacOS text editing workflow
Fixes: #18059
CMD+Left and CMD+Right are hotkeys used on MacOS for
moving cursor to start and end of the text, respectively.
They are now supported, alongside ALT+key.
Fixes: #17631
