This will be fixed as part of the update reworking that I'm doing.

*** Bug has been marked as fixed ***.

Oops, didn't commit this part yet.

CVS commit by staikos: 

change the default paint mechanism to P_PAINT from P_DATA and introduce a hack
to the update thread to pass the list of changed curves in the event.  Kst2DPlot
is a mess and too dangerous to put into the update thread right now.  This hack
will go away when Kst2DPlot gets cleaned up.

BUG: 95117
