Place capacity can be addded on Apple mouse

[Jiri Srba]

I just discovered something interesting. The apple mouse has not a wheel for scrolling, but it has a small scrolling ball which enables
to scroll also left to right and backwards.

Now if I am above a place in the editor and scroll up and down, number of tokens is increasing/decreasing. But if I scroll left to right
then the place capacity is changing (there appears a new symbol k= some number and the number is changing). It is then impossible
to place there more tokens then what is the capacity k. This is a feature from old PIPE version but we do not support it, and
it should be disabled also on Apple mice ...

And some even more funny stuff happens when scrolling left-right over a transition! It becomes from a filled box to empty box and starts to rotate! :-) At some point we have to fix (disable) this!

This bug was related to shift + scrollíng (left/right scrolling on mac), and is now fixed in latest bzr version 10.
