You're right. It seems we need the second BitBlt pass even for black 
text. Just added that to the trunk. I also added a preference, 
#properAlphaForBlackText that defaults to true, but can be set to false 
if performance is more important that correctness.

Note #1. This needs a rather recent VM, that includes my fixes to BitBlt 
done in April. Your latest Windows VM is ok.

Note #2. If the trend is to fix the handling of alpha channel in the 
image, at some point the fix to ignore Display alpha must be removed 
from the Linux VM, to play well with composing window managers.

Note #3. The second pass stuff is done in GrafPort, but not in BitBlt. 
Do you think it is better to move it up to BitBlt?
