I don't know if it is canonical and I don't have any references. Finding out
that is one of the reasons I asked on the mailing list before I start
implementing it.

I just looks as the easiest way of implementing subpixel fonts -- the font
image is used as a mask for memdraw, if the red, green, and blue channels
from the mask are used as masks for red, green, and blue channels we can get
the subpixel font drawn properly.
