Hi Herbert,
I have to admit I am pretty undecided about this. Usually I am always
in favor of patches sent to me. And I agree with you that panning is a
bit hard to control right now.
But on the other hand side I know that users don't like too many
dialogs to setup things. And especially not about parameters hard to
understand.
I played around with your patch for quite a while and it's hard to get
a feeling on how to setup the best value. Probably this is because the
algorithm I use is bad. With or without your patch.
I have a cloudy idea of accelerating panning as a function of distance
to the screen border and time. And stopping it immediately if the
mouse is moved the other direction. But it's just a vague idea.
What we can do, as long as there are only vague ideas around, is to
define a fixed value to scale it. Probably you have found your
favorite scale factor by now. Why not use this as long as there is no
better idea?
I would prefer a factor lower than 50 %, perhaps 30 - 20.
May be there are some other drawbacks with such a low factor but I did
not see one at the moment
