----------------------------------+---------------------------------------
 With the recent
 [https://github.com/yethie/FFmpeg/blob/master/drawtext/CHANGES.md big
 changes to drawtext filter] in 6.1, it seems bitmap fonts are no longer
 supported. I had been using some !OpenType Bitmap fonts (.otb) along with
 !TrueType fonts that included bitmap glyphs. Now I receive the the error
 "Monocromatic (1bpp) fonts are not supported" when I try to use them. From
 what I've gathered, harfbuzz does support otb files, but I'm assuming
 there is more to this. It would be nice to see bitmap fonts supported
 again. Appreciate any feedback.
