When using the wheel for scrolling, it actually generates a bunch of intermediate
scroll positions based on the difference between the desired and current
position.  This causes the content to scroll smoothly.

I had a devil of a time getting it so that regardless of moving 3 notches
quickly, or slowly, you would end up in the same place.  But that is clearly
desired.

I think after everyone had some time to play with Lyle's change, I may add
a similar "animated" change to the dial widget.  Again, it is visually attractive
to go through the intermediate positions, but one will always have to make sure
the rotation ends exactly at the same place regardless of how fast one rolls the
wheel.  

The intermediate positions generated by the animation mode send SEL_CHANGED
messages only, btw.

So we need the equivalent of the registry setting "wheellines" which=20
controls how many lines you scroll up/down with the wheel.
I suggest "wheeldialratio" or "wheeldialspin" or "wheeldialamount"
ah, whatever.

It works great! Next drop should include the new stuff.

Try it first.  The proportionality constant seems OK.  When rotation
stuff in the GLViewer, I can now get things to rotate in nice increments,
and achieve the standard orientations (90, 180, and so on) easily with the
wheel.  Its quite an improvement.

Have you considered adjusting the amount of spin based upon the
speed of the mousewheel? In other words, if the time delay between
each click of the mousewheel is less than a certain amount (user
spins it fast), the dial moves more for each click, whereas if the
time delay is greater (user spins it slowly) the dial moves less for
each click (fine adjustment). This is similar to mouse pointer
acceleration.
