I modified src/sfnt/sfobjs.c to handle sfnt wrapped CID bitmap font
file.  (i.e. "TrueType" without OUTLINE :)

I bundle the patch with this mail.

* FT_FLAG_FIXED_SIZE is turned on when TTF has sbits.
And FT_FLAG_SCALABLE is turned off when TTF does not have outlines.

* ftview works well.  But you want to show invalied size bitmap font,
ftview shuts "TT_Load_Glyph: could not access glyph table."

And I wrote a preliminary draft of ftdump for FreeType2.
