"""
|
|
Remote PKG Installer NextGen — bitmap font generator.
|
|
|
|
Renders ASCII 32..126 into a packed 1-bit-per-pixel glyph table
|
|
(cell 12x21, font size 15, monospace) and emits src/font_data.h.
|
|
|
|
The runtime (src/font.c) expands the packed bits into an ARGB8888
|
|
atlas texture once at startup; glyphs are tinted via SDL_SetTextureColorMod.
|
|
|
|
Usage: python3 tools/gen_font.py
