Styling

[Juuxel]

Current plan:

• JSON5-based (like Spinnery), since CSS is too heavy and there is an existing JSON5 parser bundled with LibGui (Jankson)
• CSS-like selectors
• Widgets can have a CSS-like style class, ID and a hierarchy of types (grid <- panel or just button for example)

Example of a style:

{
  button: {
    // Applies to all buttons
    text_color: 0xFF0000
  },
  "button.run_button, label": {
    // Buttons with the class .run_button and all labels
    background_color: 0xFF0000FF
  }
}

All styles are stored as assets/<namespace>/libgui/stylesheet.json5 (replace libgui with the project name if this is moved to another project). They are loaded and stacked from all resource packs.

TODO:

• For selecting things with classes, there needs to be some sort of a priority system for selectors (I'm thinking of widget ID > numbers of classes > index in type hierarchy as a simple priority system)
