Hi

I pushed a change to handle Mouse.XThreshold / Mouse.YThreshold in 
IKBD_SendRelMousePacket().

For now, if DeltaX / DeltaY are less than Threshold, then nothing is 
reported when moving mouse ; for example with a threshold of 20, this 
means you must move the mouse for more than 20 units in one go to see 
the pointer moving on screen under gem desktop.

But I wonder if that's how it works on real ST ? Do we need to move the 
mouse fast enough to get a packet (else we never get a packet) or does 
it mean that if you move slowly by 1 unit you will get a packet after 20 
units ?

If someone can test this on a real ST (by sending command $0B with 
threshold 20,20 for example) ? Else I will need to check it later, but 
my ST is in a box at the moment.
