Color wrangler for Godot

How to use ColorWrangler:

• download the WranglerAddon.zip file with the big button above
• unzip it in your Godot project folder
• you should now have an addons folder with a ColorWrangler folder inside of it
  
• open your Godot project
  • go to Project > Project Settings > Plugins
  • enable ColorWrangler
    
• when pressing the large "+" button to add nodes ColorWrangler should show up as an option you can choose
  
• adding it will create a TextureRect node with a material already applied
• change the shader parameters of that material to change behaviour, use color reference if you want to fine tune the shaders behaviour
  
  • color_palette - needed to function, takes 1pixel tall strips of color as input, find examples at Lospec.com when downloading a palette using the PNG image (1x) option like this
  • use_color_reference - when turned on reads the next parameter, otherwise treats palette as both the palette and the reference
  • color_reference - accepts same palettes like the color_palette variable above. If use_color_reference is set to true - replaces pixels closest in color to the reference image with pixels from palette, otherwise replaces pixels with their closest option in palette.

Examples of behaviour described above:
