Sorry for the late reply.  Academic life is quite time consuming in
the end of the semester.

Thanks.  Some general remarks regarding coding style: For me,
consistency is extremely important.  On the other hand, I don't want
to enforce the admittedly strange coding style of FreeType itself.  A
good compromise is the style used for the `ftinspect' demo program,
and I ask you to follow.  In particular, there are

  . no tabs, only spaces

  . two spaces for indentation

  . no lines longer than 80 characters

  . always a newline at the end of a source code file

Note that this is something for a cleaned-up branch.

Please tell me again why you want to use the BMP format and not
something more compact – I forgot the reason...

Please show images.

This sounds promising.  Again, as soon as you have a prototype,
generate images and send them to the list so that we can evaluate the
results, too.
