For instance, I set the window width to 400 pixels and then move the
mouse the trough the width of the window and add the X axis deltas up.
This value aproximates 400.
My mouse is the Logitech Mx Revolution which operates at a resolution
of 800dpi, my Monitor operates at 75dpi. How can it be that the ticks
of the mouse are in lockstep with the pixels on the monitor?

The only answer I can offer is that something downsamples a high
resolution signal to a lower resolution integer signal. In a nutshell
that is what I don't really like.

I don't know how you can get it on linux. But I remember you could get
it with directx. If I remember correctly it's quite like a joystick,
in that there's some short buffers holding the delta value, which can
be huge per inch of movement and certainly isn't in lockstep with the
pixels on the monitor.
