/* A word about NSScroller vs. wxScrollbar:
NSScroller uses two float values to represent the state of the scroller.
The floatValue indicates where the knob is positioned on a scale from
0.0 to 1.0. A value of 0.0 indicates the scroller is at the top or left,
a value of 1.0 indicates the scroller is at the bottom or right. A value
of 0.5 indicates the scroller is dead center.
wxScrollBar uses three values. The position indicates the number of
scroll units where 0 is at the top or left. The range indicates how
many scroll units there are in the entire bar and the thumb size indicates
how many scroll units the thumb takes. The scrollbar is at the bottom
or right when position == range - thumbSize.
It may be easier to consider wx position to be the top or left of the thumb.
In Cocoa, floatValue can be considered as if it were the center of the
thumb and the range is ALWAYS (no matter what the knobProportion is) the
distance between the center point of the knob from one extreme to the other.
