As a follow up,these are the two bug reports related to the above 
feature (the first one for vte, the second for gnome-terminal).
   http://bugzilla.gnome.org/show_bug.cgi?id=139333
   http://bugzilla.gnome.org/show_bug.cgi?id=139332

Given the fact that the Render operations that require reading from the 
frame buffer are quite slow with many drivers, it would probably be 
worth making it possible to disable antialiasing even in the presence of 
the render extension.
