The X server XFree86 in version 4.0 will be able to print text with
antialiasing,
by using a new subsystem. In other words, it will only benefit new applications
or applications that use an updated version of a toolkit that would perform
the rendering.
GDK can be modified to use these new features in XFree86 4.0 and then all
GDK/GTK
applications would have antialiased text.
In fact, it is possible for a GTK theme to override a function in the call chain
with a function that would draw antialiased text. (GtkStyleClass::draw_string())
I was thinking of doing that in my own GTK theme (Xenophilia) which would print
a
specific font with antialiasing.

I have seen X/GDK do the same thing, i.e. scale up bitmap fonts.
For instance, in your .gtkrc you can set it to use a bitmap font with a size
that it
does not have and then X will take the closest font and scale it.
I don't know which functions to call, or how to call them in order to get
scaled bitmap fonts.
