* Implement 3D layers
* Remove unneeded files
* Fix bug where a single hidden layer would ignore all of the layers on top when exporting
* Fix pxo loading
* Remove junk nodes from 3DShapeEdit
Seems like they were created when I copied from the old 3D Options.tscn panel to the new 3D Shape Edit tool.
* Make light gizmos half the size, and hide gizmos when rotating
* Fix crash when using the 3D shape edit tool on a group layer
* Remove unneeded code in Canvas.gd
* Add torus in the Cel3DObject.Type enumerator
Torus isn't currently supported in Godot 3.5, but it is in 3.6 and 4.0, so this is just future-proofing. May break compatibility with .pxo files that were exported with 3D layers before this change.
* Toggle 3D object visibility
* Change texts and some variable names
* Fill translation strings
* Fix crash on group blending, and make the code in Export.blend_layers() more general
* Fix errors when attempting to draw on a 3D cel
Can occur when multiple cels are selected, some of them 3D and some of them pixel
* Make scene properties and objects be per-cel instead of per-layer
Breaks compatibility with previous .pxo files that had 3D layers. Also introduces serialize() and deserialize() methods to BaseCel
* Use if not layer is get_script() in GroupLayer.blend_children()
* Flip the condition in GroupLayer.blend_children()
* Fix bug where locked/invisible layers could get drawn
Regression from c2f6bf0f3f
* Move gizmo code to 3DShapeEdit's draw_start(), move some undo/redo logic to 3DShapeEdit
* Move all of the undo/redo code to 3DShapeEdit, simplify code in Cel3D
* Store Cel3D image data to pxo, for easy usage by external software
This makes importing projects with 3D layers to other software, such as Godot using godot_pixelorama_importer easier.
* Make the linter happy
* Fix bug where the previously selected object would remain selected when it got removed with undo
Also fixes a bug with the inconsistent behavior caused by resizing a selection with gizmos without pressing Shift, while the keep ratio button was pressed.
For some reason, cel_texture.texture.get_data() seemed to cause a segmentation fault, and then a crash, when the image size was large. Also added some extra static typing to the drag and drop methods, but they are unrelated to the crash.

Have only two shaders, one for simple gradient and the other for dithered gradient generation. The gradient shape gets passed as a uniform to the shader. Gradients can now get repeated, and the size option for linear gradients is back.
Gradients are no longer limited to two colors, but can now instead have as many as we want, with each color having its own offset. Step gradients have now been removed; to generate the same effect, you can now generate a linear gradient with constant interpolation. Cubic interpolation in gradients is now also possible.
The dithering shaders were by far the biggest challenge and they had to be re-written in order for them to support multiple colors, with each one having a difference offset. I have noticed that some colors may disappear when Constant interpolation is used, though, so it can be buggy sometimes. Thanks to https://godotshaders.com/shader/dither-gradient-shader/ for the reference.
ValueSliders are now also used in the gradient window.
Snap to the rectangular grid and guides (excluding symmetry guides). Can be toggled from the View menu. Currently affects the following tools: Pencil, Eraser, Shading, Line, all shape tool and all selection tools. Although maybe this should not affect the Magic Wand and Select By Color? The snapping distance is currently unaffected by the zoom (should change), and it will be exposed as a parameter in the preferences at a later commit.
This commit removes the unnecessary point_in_rectangle() method, as Rect2.has_point() can be used instead. I was not aware that this built-in method existed back then.

* Moved the rest to their respective folders
* formatting

I removed the `PackedScene` static typing declaration to reduce the number of characters in the line to less than 100. It's not really needed anyway, as Godot should be able to figure out that it's a PackedScene, since it's a tscn file, simply by using `:=`.

Using a signal to change the cel was not a good idea, because it was not being emitted with the undo/redo system. The signal should also fire *after* the cel changes, and this is what happens in this commit. Should be useful for future features and extensions to check whether a cel has been changed.
A small refactor. A very minor performance boost when selecting cels, but also a minor performance decrease when selecting frame buttons. Selecting layer buttons should be pretty much the same. I think the code should be a bit more readable now, plus we got rid of that yield() in Project.gd so that's a bonus.
* Allow floating point for HRuler

* Implement clear4x rotation

* Update to cleanEdge algorithm
* Add cleanEdge scaling
Removed `directory_path`, `file_name`, `file_format` and `was_exported` from Export.gd. These variables already exist on Project.gd, no need to have them twice.

This prevents common shortcuts like CMD+S (Save), CMD+C (Copy), etc, from activating a tool.
* Fix formatting

If you press and hold an arrow button, the value will keep changing until you release. Replicates SpinBox's behavior. We should be able to replace any SpinBox now without losing any functionality.
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.

Paste now places the pasted content in the middle of the canvas view, instead of its original position. A new option in the Edit menu has been added, "Paste in Place", that preserves the previous behavior. This is similar to how GIMP works.
This eliminates the need of the dialog having a rect_min_size, which lets users resize it to make it even smaller. The OK button is being hidden at the start, so visually it should look almost the same.
