Vendorea el set de iconos Tabler (~5500 iconos, MIT) para usar en apps
ImGui via icon_font_cpp_core. Incluye:
- tabler-icons.ttf — atlas TTF para mergear en ImGui
- tabler-icons.css — referencia de codepoints (no se compila)
- gen_header.py — script que regenera cpp/functions/core/icons_tabler.h
con macros TI_<NAME> a partir del CSS
- LICENSE / README.md — atribucion MIT
Versionar el TTF (~700 KB) evita depender de descargas en build. Las apps
usan TI_* en strings y el atlas se carga con icon_font_cpp_core::load().
