I tried to do something similar and had similar problems. I was never
able to duplicate the system fonts, though I was able to get close
with Lucidia Console.

Try FT_LOAD_MONOCHROME. You should also play around with hinting. I am
not sure how to change this in Microsoft's API. You can compare your
results to Microsoft's renderer by passing NONANTIALIASED_QUALITY to
CreateFont for antialiasing.

It might be wise to abstract your API so that it can support more than
one font engine.

I do not have much more information. I am still working through this
myself, though I have mostly given up until I can get more information
from somewhere.

Please make sure you post to the list - on some mailing lists, you
need to hit "reply all."
