Making it consistent with its image effect counterpart. The code inside ShaderLoader.gd keeps getting uglier and uglier, it might be worth a refactor at some point.
Massive thanks to Material Maker for the custom widget code. The color curves effect is still WIP, I need to make the tangent points visible (not yet sure why they aren't now), add some curve presets, and implement it as a layer effect as well.

* Blend group layers on `DrawingAlgos.blend_layers()`
* Support group layer blending on the canvas
* Allow editing of group layer properties
* Fix issues with group layer blending in canvas, and unite common code
* Group layers can now be used as clipping masks
* Make move tool preview work on child layers
* Change OffsetImage's `blend_layers()` to support group layer blending
* Support group layer blending in the canvas preview
* Fix layer blending mode, clipping mask opacity and cel opacity not being updated automatically if the layer/cel changed is not selected
* Add a pass through blending mode to layer groups
Fingers crossed that no bugs were introduced
* Fix issue with layers that belong to pass through groups not updating their textures on the canvas automatically on undo
A slightly breaking change for a minor update, but one that needed to be done. The bucket tool's "similarity" (now renamed to "tolerance") used to work the opposite way from all other software, the maximum value meant exact color match and 0 meant no color match. Now it works the inverse way to make it be consistent with other software, and the range is now 0-255 instead of 0-100. 0 means exact color match, 255 means no color match. And tolerance also now works for the "similar area" mode as well.

The shader has more options than just brightness and contrast though, but I didn't know how else to name the effect. "Adjust Brightness/Contrast" makes it immediately obvious as to what the effect is about.
This will allow us to implement shearing more easily. Also, for the non-SmearRotxel shaders, normalize their pivot in GDScript, before passing it to the script. Should probably be faster this way
Pixelize makes the image pixelated, and Palettize maps the color of the input to the nearest color in the selected palette. Useful for limiting color in pixel art and for artistic effects.
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.
* 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
Looks like some kind of textureSize() bug with sampler2DArrays when accessing the z member. I have only confirmed this bug on an AMD GPU. Nevertheless, it should be fixed now with this workaround.

There are some errors due to the usage of anonymous lambda methods in undo/redo, but it seems to be working well regardless.
