SVN commit 581495 by harris:

Cleanup KPlotWidget

KPlotWidget:

- added setAntialias(bool), set to true for smoother (but slower) 
plots

- removed explicit double-buffering (Qt4 does this automatically)

- added top and right axes (by default, they show the same tickmarks 
as bottom and left)

- added optional secondary data limits for showing alternate 
set of tickmarks on top and right axes.

- removed setShowTickMarks() / setShowTickLabels()...each axis now 
handles its own visibility logic.


KPlotAxis:

- each axis now calculates its own tickmark positions (rather 
than KPlotWidget)

- rather than setting the number of tickmarks and distance between 
them, the tickmark positions are now stored in a QList<double>

- simplified visibility logic: 
  + isVisible() : draw axis and tickmarks ?
  + showTickLabels() : obvious
  + the axis label is drawn if it is not empty

- added new ticklabel format 't', which indicates that the ticklabel 
values are decimal hours, and should be rendered with a clock-time
format ("hh:mm").  Other special format flags are possible.


I didn't have to modify kalzium or ktouch, so the API hasn't 
changed too much.  Most of the changes are "under the hood".

I also didn't look at kmathtool, since they have their own copy 
of KPlotWidget in the playground.  I'll let them decide if and when 
to use this version.
