>I had tought on an unclean alternative to have a higher time >resolution on gdk/gtk+ events, that would be to have a core GIMP time Is there any other way to read the mouse positions than via X? I would like to completely separate the mouse device and the graphics drawing because GTK drawing caused jitter in mouse readings. When I move the mouse in circle slowly, the drawing is detailed. But when I move the mouse fast, the drawing is polygonal. Is the reason in mouse interface or in X, or both? Does the tablets have the same problem? Are the fast drawings in GIMP 2.0 still polygonal? Could that be fixed with splines? Should the spline system be inside the mouse system, not inside the drawing system? I.e., some kind of simulated high time-resolution mouse (or tablet)?
