Nope, they're defined as integers by Xlib interface (at least for X11R6.4). I 
don't know the why GDK uses floating point there, but I'll not be surprised if 
it smth ~= "historical reasons".
Maybe this question is for gtk-devel list ?

That becomes a problem when 450MIPS CPU can provide <= 2MFLOPS.

Some time ago I was thinking about to run GTK2 on embedded device (without FPU 
also). Project was freezed at the point when I started to look for alternative 
toolkit.
