Simple outline

[Nathan-M-code]

Hey ! I would like to do a simple outline around my text.
I didn't find anything "ready to use" in glyphon nor cosmic-text, I assume I have to handle it myself.
I found custom_glyphs in TextArea, I thought of adding for each glyph an other one bigger, but maybe the order of rendering will be wrong.
So maybe is it better to just have another Buffer.
What would be the easiest way to go ?
Thank you
