Applying text outline

[toricray]

I want to understand how text outline is applying, but I cant find the answer in code.

Text has m_vertices and m_outlineVertices. Text::ensureGeometryUpdate function adds glyphs to them.
My question is: how glyph without outline are centered in outlined glyph?
Its better described in an attached image:
1st letter is sf::Text, 2nd letter is my attempt to recreate it from two sf::Glyph`s.
How to make proper padding betwen regular and outlined glyphs?

I don't fully understand how it works either, looking at the code however it seems like it should set the bounds of the glyph correctly already. I'd assume that the outlined glyph might end up with a negative glyph bound.
At least I can see any special padding going on, but SFML directly uses the glyph's bounds: https://github.com/SFML/SFML/blob/master/src/SFML/Graphics/Text.cpp#L534-L557
