Well, the app has to tell the video driver/hardware/whatever _what_
things to erase/draw.  If it's lazy (like Defendguin) and says
"erase everything... now, redraw this, and this, and this, and this..."
there's no chance for the video card to make things easy on the CPU
and, in a thin-client situation, the network.

So, again, apps like Tux Typing 2 should provide some less graphics-intensive
options for people stuck with lower-end networks (10Mbps and 100Mbps)
in their thin client setups.  Just my opinion, of course.  I have no
real-world experience with K12LTSP. :^/
