QwtPainter

QwtPainter::polylineSplitting has been reenabled. Unfortunately the Qt raster paint engine still has serious performance issues with rendering long polylines.

QwtPlotCurve

- QwtPlotCurve::adjacentPoint
  for monotonic curves: using a binary search algo

- QwtPlotCurve::interpolatedValueAt
  for monotonic curves: using a binary search algo

QwtSeriesData

- wrong inheritances fixed
- firstSample, lastSample added

QwtPlotIntervalCurve

QwtPlotIntervalCurve::TubeAsLines mode added. A performance optimization
for rendering huge datasets.
