[Kst] Infinite recursion

[George Staikos]

When I switch to data mode and mouse-over a plot generated by piolib that 
contains holes on the left and right, it goes into the infinite loop pasted 
below.  This is the same problem I had quite some time ago and fixed with the 
_highlighting variable, which was removed in r1.341.  The stack trace 
demonstrates how the recursion happens.
