Integrate stb_truetype.h to rasterize TTF glyphs into 1-bit .FNT v3 format consumed by Win3.x display drivers. Key implementation detail: .FNT bitmaps use column-major byte order (all rows of byte-column 0 first, then byte-column 1, etc.), not row-major. New API: wdrvLoadFontTtf(path, pointSize) loads any TTF at any size. Demo 7 renders Liberation Sans/Serif/Mono at 16/20/24pt. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# 16-bit driver calls via thunkCall16, causing wrong values in drawing

# parameters. Disabling GCSE changes the layout enough to avoid the

# call thunkCall16 with interleaved parameter setup).
