This will be the parent of all (or most) image effect dialog nodes. Currently only parent on FlipImageDialog, will change to be parent of the rest of the effects.
This comes with the benefit that we no longer need a Viewport node in the ShaderEffect dialog, which lets us have the Preview TextureRect at a fixed size. Previously, the preview was scaled based on the image's size, which would make applying shaders to large images very inconvenient, since the dialog would be way too big.
Not sure if options for RGBA channels are really needed here, but I kept them from invert colors. We could remove them in the future if they are unneeded.
* Split export code from export dialog to Export.gd autoload
Clean access to child nodes of export dialog
* Fix export variables set in Main.gd
* Fix more wrong variable assignments

If the loaded shader has uniforms, they will be exposed to the UI, so the users will be able to modify the shader parameters easily. Currently only works with float uniforms.
This new feature allows users to load a .shader file (must be a GLES2 Godot shader) that will modify the image itself. This feature is experimental and possibly buggy, not all shaders are working properly and I'm not sure yet why. As such, this feature may not be included in v0.8 stable.
First option is to affect the selected pixels only. The second it to affect the current cel, or the entire frame (all cels of the frame). Options to affect all frames and all projects will be added next. I also made changes to Canvas.handle_undo() and handle_redo() to make this work.
Once all these options are added successfully in HSVDialog, they will also be added in the rest of the Image effect dialogs.
This will allow us to create more selection tools in the future, that aren't necessarily rectangular (See #129) and even enhance the current rectangle selection tool (See #56)
Current issues spotted so far:
Drawing is slower for large images, and bucket filling is also considerably slower even on a 64x64 image. Optimizations are required.
The default image width, height and fill color are being used only when the program first launches. After that, if the user creates an image with changed settings, these settings are being kept.
