    For each element group definition there is a comment specifying the color used
    in Godot editor's default theme to highlight that particulare element. This is
    to help keeping track of the various elements during tests, and to create a
    stylesheet mimicking the original look and feel of Godot's editor.
    Color here are given as hex values representing them as they appear on screen
    (unlike Godot theme files, which contain alpha values).
    Color names were calculated using NTC (Name That Color) tool:

--[[================================= DEV NOTES ==================================
    ESCAPE SEQUENCES were modeled according to Godot source code:
    "/modules/gdscript/gd_tokenizer.cpp" (lines: 604-)
    
    The following escape sequences are matched by 'Escape' RegEx:
      \a   \b   \t   \n   \v   \f   \r   \'   \"   \\   \/
    
      \uhhhh (universal character names): "\u" followed by four hex digits (h)
              representing a Unicode code point.

    NOTE: Hexadecimal (\xhh...) and Octal (\nnn) escape sequences are unsupported
          as they appear to be depreacted in GDScript ("gd_tokenizer.cpp":619).
