For the planned mf2pt1 conversion it's quite simple:

 . Don't use `draw' with anything but `penrazor'. 

 . Don't use `filldraw' with anything but feta_fillpen -- this expands
   to a 1-pixel wide pen if run with mf and a nullpen if run with
   mpost.  If you want to use `filldraw', use the proper `top', `rt',

 . Don't use `---'.  Replace it with `--', specifying the curve

For good pixelations, the following is needed:

 . Tangent points of curves should have integer coordinates (in the
   specific direction).

 . If you want to draw identical shapes repeatedly, use an integer
   offset for shifting.

 . For symmetrical glyphs (or glyphs which should be positioned
   exactly between or on staff lines) read the comment in

There are some other subtle things which I will eventually collect in
