A very simple implementation, not as complex as something like #768 yet, but it can be done in the future.
The main current limitation is that it doesn't work with group layers as of right now.
* Update 3DShapeEdit.tscn
Change the menu button to flat to indicate that it is a button that you can press and not a label
* Changed Signal names to make sense
Note: I did not change functions in the ExtensionsAPI
Changed signals in Global.gd (and everywhere else they are referenced) from *_changed to *_switched
* Bonus Signal
Added a signal in Global.gd that gets emitted just before the project is changed.
Added project_changed to Global.gd which also emits what project was changed by an action (not switched).
* Formatting
* Reference Image Updates
* Fixed static typing
Fixed static typing in "src\UI
\ReferenceImages\ReferenceEditPanel.gd"
Changed "ri == null" to "!ri" in "src\UI\Canvas\ReferenceImages.gd"
* Tried fixing the static typing again
Removed lambda functions for the confirmation dialog.
Removed irrelevant print statement.
* Tried fixing static typing again
I think its fixed now
* Changed Spacing
* Fixed Trailing Whitespaces and tabs
* Fixed Final Trailing Whitespace
* Fixed styling and removed useless enum
* Removed double tabs left over from previous commit
* Fixed remove ConfirmDialog Showing on startusp
* Tried Fixing gdlint issues
* Fixed Linting
* Fixed Spelling issues
* Drag and drop to rearrange reference images
Added the ability to drag and drop Reference Images similar to dragging and dropping layers. These can be dragged or used with buttons (similar to the buttons that move frames). With full undo/redo support.
Added tool buttons these should help people who draw on tablets that cannot use keyboard shortcuts (icons still need to be created)
Renamed ReferenceEditPanel.gd to ReferenceEdit.gd (because it is no longer the script of a panel) and changed the base class of the Reference Panel.
Added some more translations.
Remade ReferenceImageButton.tscn to allow for drag and drop
Added drag highlight
* Added Icons
Added icons for the tools of the Reference Images
* Applied the icons to the UI
* Fix Scripting Issues
* Fixed Linting
* Rename Move.png to move.png
* Update Canvas.gd
* Updated the tooltips
Also added the correct translations
* Rename Select.png to select.png
* Rename Select.png.import to select.png.import
* Rename Move.png.import to move.png.import
* Rename Rotate.png to rotate.png
* Rename Rotate.png.import to rotate.png.import
* Fixed import files
* Rename Scale.png to scale.png
* Rename Scale.png.import to scale.png.import
* Added logic to update the reference panel when the project changes
Also fixed visual bugs related to highlighting the current reference image.
Made it so the reference image that was selected in a project get selected again when the project opens instead of going back to -1 (nothing)
* Update Project.gd
* Basic logic for layer effects
* Add an FX button and the ability to add effects, no way to remove or change properties of effects yet
* Basic and ugly UI for adding and removing effects, no property changing yet
* Swap effects
* Fix preload shader paths
* Change parameters for layer effects
* Change gradient parameter in layer effect shaders, and other fixes
* Use CollapsibleContainers for the shader properties
* Set the correct gradient interpolation mode and color space in the UI
* Make effects of group layers apply to children
* Change `apply_fx` to `apply_effects`, formatting, some extra doc comments
* Apply effects to other canvases, when merging layers and when exporting
* Display humanized names of the shader unifrms
* Some UI improvements to the LayerEffectsSettings
* Add an Enabled button in the layer effects window, and change checkboxes to checkbuttons
* Change BaseLayer.apply_effects() to take a cel as a parameter instead
* Make layer effect buttons be affected by the modulate icon color
* Add option in the View menu whether layer effects are displayed in the canvas or not
* Rename `apply_effects()` to `display_effects()`
* Add translation strings
* Add nearest filter to the gradient map
* Don't change Main.tscn
* Fix more translations
* Change the default cursor shape of the generated UI elements of the layer effects
* Add undo/redo and effect application (apply effect destructively)
There are some errors due to the usage of anonymous lambda methods in undo/redo, but it seems to be working well regardless.
* Make layer effect application work on all cels
