* Some docstrings
* More Vector2i and Recti replacing their float counterparts
* Remove the hardcoded shortcut from ValueSlider
Note that the brush size shortcut may not change properly because Keychain isn't updated to support Godot 4's input map properly yet.

* Fix bug where some imported images would fail to load when using smart slice
* Fix integer zooming (I think)

* Change OSX to macOS
* Detect if multi-threading is enabled when exporting gifs
* Fix color picker not working on the top color mode
* Make some public methods private in Export.gd
* Remove Global.window_title variable
* Fix frame UI in the timeline breaking after 100 frames
* Static typing improvements for the timeline
* Better static typing for grids
* Fix typo
* Fix pixel grid not appearing
* Move preference updating code to Global using setters
This should make the code a bit more readable, as the logic for each property update can be found directly under the variable declaration, and not hidden in PreferencesDialog's preference_update() method. This also allows for changing these properties outside the preferences, if that will ever be needed. In theory it's also faster as we don't have to do all these string comparisons anymore, but I doubt this will be noticeable in practice.
* Remove RestoreDefaultButton.tscn
* Implement changing font size in the preferences
* Resize HeaderSmall font size along with the default font size
* A step towards fixing image loading in the Web version
Doesn't completely fix the issue, it requires a fix from Godot's side as well
* Implement missing input event actions for buttons
TODO: Add default shortcuts
* Do not change language and theme if they are already the defaults
Reduces the initial loading time a bit
* Remove update_hint_tooltips() as it's no longer needed, only keep it for tools
This was needed in order for hint tooltips to be successfully translated while taking the shortcuts into account. Godot 4 already it correctly for us now. Tools still need it because they contain multiple shortcut data in their tooltips.
* Change ExportDialog's PathDialog's file mode to be "open directory" and make them bigger

* Image bruch now obeys dynamics as well
* Added a signal that resets dynamics
* formatting
* change uncheck.png
* added preview for pressure
* Added the requested changes
This lets us create ValueSlider and CollapsibleContainer nodes properly via the add node button, instead of instancing their scenes. They have also become more a bit more themeable. Eventually, ValueSlider.tscn and CollapsibleContainer.tscn will be deleted.
Their visibility is toggleable. They also currently do not support echo events, since for some reason Godot only supports them for InputEventKey(s). I suppose this feature could be replicated with a Timer. Once this is done, we can replace all SpinBox nodes.

* Add 6 shader-based gradient types
* Shaders now respect selection
* Fix step gradient
* Remove comments
* Disable step and dithering shaders in Web version
* Fixed a weird bug with dithering shaders, selection and GLES2
Having a selection, applying a dithering gradient, removing the selection and then going to the gradient dialog again causes the dithering shaders to "remember" the previous selection, even if there is no selection currently. This only happens with the two dithering shaders and only with the GLES2 renderer. Removing `uniform sampler2D dither_texture;` from the shader code seems to fix the issue, but that's obviously isn't what we want so a "proper" fix is included in this commit.
* Format & lint
* Removed old gradient code
* Change how centers work on radial step and dithering
* Made angle, center and radius option a bit more clear
* Rename bayer-matrices directory to dither-matrices
* Use DitherMatrix class
* Create dithering types programmatically
* Remove unneeded code in shaders
* Rewrite the step shader without a for loop
More optimized and works on the Web version with GLES2
* Rewrite radial step and dithering shaders without for loop
Now all shaders work on the Web version and have been optimized.
* Fix Linear & Radial size range and remove some unneeded lines
* Added size uniform to Radial Step and Radial Dither
* Swap colors in the Linear gradient
* Make size a percentage
* Make the preview look the same as the result
Didn't change the dithering shaders because they seemed to give different results.
* Remove ratio uniform and divide uvs by the radius instead
This makes more sense because the smaller the number, the smaller the radius.
* Fix linear gradient
* Change Position to percentage and "Size" to "Transition size"
* Mix gradients with original color, if the gradient colors have transparency
* Add dockable container plugin
Experimenting with it, also added a tabs_visible property to the DockableContainer. Removed some code about Tallscreen from Main.gd, but not all of it.
* Add a panel behind the UI, temporarily restore the dark theme
* Remove tallscreen code
* Add edit mode, toggles DockableContainer's tab visibility on and off
* Split tool options into color pickers, left and right tool options
* Remove alternate_transparent_background
* Re-order tool buttons on resize
* Clip content in timeline
* Changes to the tool panel
* Removed some old unused node variables
* Restore Zen mode
* Set tabs_visible = false by default
* Better way to set tabs_visible = false by default
* Added the license of godot-dockable-container
* Remove unneeded lines
* Update README.md
* Restore window transparency with the canvas
It makes all of the TabContainers transparent however, which may not be what we actually want.
* Change tab names of the UI elements
* Remove unneeded nodes from ColorPickers.tscn
* Update default.tres

* Add some checks in HandleThemes
* Center tool icons
