Couldn't the helper function pfuCalcNormalizedChanXY have been folded into
the methods of pfChannel ?

It seems to me that you want to use this call in conjunction with
pfChannel.pick most of the time. pfuCalcNormalizedChanXY pulls out the
origin and extents of the channel to normalize the mouse screen
coordinates. It would be cleaner to just call an overloaded version of
pfChannel.pick with either floats or ints for the mouse position -- floats
for already normalized coords and ints for mouse screen coords. This is
probably too obfusicated, but at the least a separate call for pickScreen
and pickNorm would work.

Anyway, I just wondered what the design decision is behind why
pfuCalcNormalizedChanXY is separate from pfChannel.

Thanks,
