Its easier said than done. The renderers do not see all load_flags but
only the 4-bit (0-5 actually) render_mode enum. I can pass the
FT_LOAD_BITMAP_METRICS_ONLY flag to FT_Render_Glyph at bit 5 or above
to force the renderers to bail once the bitmap metrics are set. Can I
set a bits in enum? This technically changes the type from
FT_Render_Mode to int. Unfortunately, the enum persists deep inside.
Any other ideas?
