[Squeak-VMdev] wheel/scroll mouse logic

[John M M. <jo...@sm...>]

In making changes to sq.h I discovered that I had made a change for the  
scroll mouse logic which impacts some changes we want to
make for multiple windows, but I not sure anyone is using this feature.

On os-x if you are using a wheel mouse I generate a mouse move event  
and pass up
the axis direction and number of movements in the reserved fields,  
followed by the key-down/key char/key-up events
for each simulated arrow key.

I believe other platforms just provide the key stroke data and do not  
pass up the raw wheel mouse data. As mentioned earlier this
data is provided in the two reserved (undocumented) fields of the mouse  
event from EventSensor.

In looking at what is happening in the image, I can't see anyone  
actually using this data at this time.

Because of changes we're making I'm going to be dropping this  
information, since it's not duplicated on other platforms, this is
an easier choice than adding another field to the event logic to  
support the windowIndex information.

  If anyone has issues please let me know.
