AFAIK this is wrong. Mouse pointers are handled deep in the bowels of X 
for the sake of performance; I'm pretty sure it uses some kind of 
hardware acceleration. The kind of "emulated" mouse pointer you describe 
would, I suspect, be horrifically slow and ugly.

Java-only apps can't reach down into the platform like that, hence the 
platform-specific DLL / .so. Whatever other transgressions the mfr may 
have committed, they're innocent on this one. :-)
