DisplayServer::screen_is_touchscreen will likely never utilize its
parameter p_screen.
This PR replaces this function by DisplayServer::is_touchscreen_available()
with the same functionality.
This solves the problem, that a SubViewport was used for determining
the screen, which resulted in error messages.
Removes separate `Command` key (use `Meta` instead).
Adds an event flag to automatically remap `Command` <-> `Control` (cannot be set alongside `Control` or `Meta`).
`set_tooltip` -> `set_tooltip_text`
`get_tooltip` -> `get_tooltip_text`
For consistency:
`get_button_tooltip` -> `get_button_tooltip_text`
And the `tooltip` parameter in `add_button` was renamed to `tooltip_text`
Affects a lot of classes. Very thoroughly checked signal connections and deferred calls to this method, add_do_method/add_undo_method calls, and so on.
Also renames the internal `_update_callback()` to `_redraw_callback()` for consistency.
Just a few comments have also been changed to say "redraw".
In CPUParticles2D, there was a private variable with the same name. It has been renamed to `do_redraw`.
Add "generate_mipmap" font import option.
Add some missing features to the Sprite3D.
Move BiDi override code from Control to TextServer.
Add functions to access TextServer font cache textures.
Add MSDF related flags and shader to the standard material.
Change standard material cache to use HashMap instead of Vector.
* Instead of containing single animations, AnimationPlayer now contains libraries.
* Libraries, in turn, contain the animations.
This paves the way for implementing the possibility of importing scenes as animation libraries, finally allowing to import animations separate from the 3D models.
Missing (will be done on separate PRs):
* Make it possible to import scenes (dae/fbx/gltf) as animation libraries.
* Make it possible for AnimationTree to import animation libraries on its own, so it does not rely on AnimationPlayer for everything.
