* Create a custom PixeloramaImage class, initial support for indexed mode
* Convert opened projects and images to indexed mode
* Use shaders for RGB to Indexed conversion and vice versa
* Add `is_indexed` variable in PixeloramaImage
* Basic undo/redo support for indexed mode when drawing
* Make image effects respect indexed mode
* Move code from image effects to ShaderImageEffect instead
* Bucket tool works with indexed mode
* Move and selection tools works with indexed mode
* Brushes respect indexed mode
* Add color_mode variable and some helper methods in Project
Replace hard-coded cases of Image.FORMAT_RGBA8 with `Project.get_image_format()` just in case we want to add more formats in the future
* Add a helper new_empty_image() method to Project
* Set new images to indexed if the project is indexed
* Change color modes from the Image menu
* Fix open image to replace cel
* Load/save indices in pxo files
* Merging layers works with indexed mode
* Layer effects respect indexed mode
* Add an `other_image` parameter to `PixeloramaImage.add_data_to_dictionary()`
* Scale image works with indexed mode
* Resizing works with indexed mode
* Fix non-shader rotation not working with indexed mode
* Minor refactor of PixeloramaImage's set_pixelv_custom()
* Make the text tool work with indexed mode
* Remove print from PixeloramaImage
* Rename "PixeloramaImage" to "ImageExtended"
* Add docstrings in ImageExtended
* Set color mode from the create new image dialog
* Update Translations.pot
* Show the color mode in the project properties dialog
* 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
You currently cannot move multiple cels on different layers, they still act as swapping. Eventually I'd also like to implement moving cels between different layers, but they would also have to be on the same frame. I don't think moving cels between different layers and frames at the same time is possible.

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.
Closes #1061, fixes issue where when Pixelorama's window loses focus, the dialogs disappeared, but the dialogs can no longer close when pressing outside of them.
* splash ambient
* change fill to radial
* make import tag work with frame button
* hide Import tag dialog when clicking outside
* Icon shows the first frame of a tag
* formatting
A few buttons and labels in Pixelorama weren't getting updated when changing languages, they'd just remain at the language the program started up with or only update when changing projects.
This fixes that and ensures they get updated as soon as the user changes languages.
The "Animation plays only on frames of the same tag" button has been moved to the general timeline settings, along with a new slider that resizes the cel buttons in the timeline.
Similar to 7507206726 but for layers. Layer swapping (with control) only works when one layer is selected. The move up/down buttons in the timeline only work with one layer as of this commit.
