Yes - and a GREY8 mask acts as the alpha channel.

Other things...

sub-pixel rendering is used to apportion the amount of alpha set in the
lower-res pixels.  In the case of freetype, this is the grey level (how black the pixel is)
this maps directly to the use of a GREY8 mask as alpha.

I have ported freetype to Inferno, as a system module, and have limbo tools for generating
font and subfont files.

My aim is to produce a scalable font server.
