Hm, would be a relief to have suport for the cursor in the library, as
this is something most of the developers would want to have but have to
code on their own each time;

Ah. but there could be a software emulation for those cards that don't
provide it;

To get all pending events out of the queue; also those I'm not interested
in, they simply get thrown away;

this is what I wont to have; why should I wont to have the queue fill up
constantly?

Ah, I understand;

But move events will fill up in the queue;
So I'll get an overflow of the queue after some time?

No, nothing was drawn, only the cursor position was saved in two
variables;
Would make me wonder if there is no hardware cursor, because the Matrox
Millenium card is
one of the best suported cards in the X server.
