Ivailo Monev 61333c4671 generic: namespaced Qt4/Katie build fixes
most of the changes were done trought Katie's namefsck script which
convertes forward class declarations to include directives, however
other fixes here and there were needed as well as some questionable
changes to Q_DECLARE_TYPEINFO() macro calls because they most likely
have to do the namespacing themselfs (QT_BEGIN/END_NAMESPACE, and
probably will be in Katie) meaning that some of the changes may be
temporary and reverted later.

This library provides the KPlot* classes.

KPlotWidget is a QWidget-derived class that provides a virtual baseclass 
for easy data-plotting. The idea behind KPlotWidget is that you only have 
to specify information in "data units"; i.e., the natural units of the 
data being plotted.  KPlotWidget automatically converts everything 
to screen pixel units.

KPlotWidget draws X and Y axes with tickmarks and tick labels.  It 
automatically determines how many tickmarks to use and where they should 
be, based on the data limits specified for the plot.  You change the limits 
by calling setLimits( double x1, double x2, double y1, double y2 ).

Data to be plotted are stored using the KPlotObject class.  KPlotObject
consists of a QList of QPointF's, each specifying the X,Y coordinates
of a data point.  KPlotObject also specifies the "type" of data to be 
plotted (POINTS or CURVE or POLYGON or LABEL).
