Instead of drawing individual lines, execute draw_isometric_tile() multiple times. What this method does is basically draws a single isometric tile, which then gets repeated for the entire canvas size. Also moved all the grid logic to a new script, which gets updated less often that Canvas.gd, for optimization purposes.
Works better than the previous method, although it might be a bit slower, and currently does not work well if the canvas size is not divisible by the grid size. For now, it only gets affected by the grid width. Changing grid height has no effect.
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.
Also fixed issue with "Show Guides" view menu option and having multiple projects with guides. Only think remaining is to make the Symmetry Guides look different than regular guides. Closes #133.
Two special guides - one horizontal and one vertical - that let you change the axis of symmetry for mirroring. On the next commit(s) I will make them visible only if mirroring is toggled on. Almost solves #133
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.
