#include "core/templates/lru.h"
Replace most uses of Map by HashMap * Map is unnecessary and inefficient in almost every case. * Replaced by the new HashMap. * Renamed Map to RBMap and Set to RBSet for cases that still make sense (order matters) but use is discouraged. There were very few cases where replacing by HashMap was undesired because keeping the key order was intended. I tried to keep those (as RBMap) as much as possible, but might have missed some. Review appreciated!

Perfect FreeType-based outlines for DynamicFonts - 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.

Perfect FreeType-based outlines for DynamicFonts - 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.
