- Implement outlines based on FreeType Stroker API. This allows
artifact-free results, similar to what you will see in Web or any text
editing tools. Outline is a part of DynamicFont rather than Label,
because outlines have to be baked into the font's atlas. Font has a
default outline_color and a Label can specify font_outline_modulator
that will be multiplied with the Font's color to get the final result.
- draw_char now has to be called twice to fully render a text - first
with p_outline == true for each character and then with
p_outline == false for each character.
- Number of draw-calls is reduced from 5 to 2 per outlined character.
- Overall cleanup of DynamicFont code, extracted duplicated code pieces
into separate methods.
- The change is backward-compatible - Labels still have outline
properties that work exactly as they worked before.
Closes#16279.
