I looked at example1.c and its passing this in with the params arg for
FT_Outline_Render.
I'm calling FT_Render_Glyph. Any idea how I can setup a callback in
this case?

I believe that example1.c does this and even provides a sample
call-back that implements the threshold you are talking about.

If you are using the 'grays' renderer you could always use the
call-back routine. Then instead of assigning a value from 0 to
255 use a scaling factor to push the values closer to 255. Of
course you glyphs will look a little fatter.
For example, add (say) 64 to each pixel value then if the
result is > 255, set it to 255.
Or, multiply the pixel value by (say) 1.5. Then set any values
>255 to 255.

I'll give this a try. Where/how do you register the callback
routine? As for "fatness" of the glyphs, maybe instead of pushing
the values brighter, I could have a threshold and zero out
anything below that threshold?
