Congratulations on finding the 'magic' combination of bitBlt rules.
I'm not sure where that leaves my bitBlt rule 41. Possibly rendundant.
But unfortunately I don't have much free time to change the FreeType stuff to use your technique.
Maybe one of the Pharo developers can make the necessary changes.
Of course I also added the gamma correction, and the handling of translucent text foreground colours.
So, it may be worth keeping both techniques around for a while.
