For now I am just calculating them quickly, using a simple algorithm. I
still need to add some method of modifying the number of bins etc.

vtkMathUtilities is header only, doesn't derive from vtkObject.

Change-Id: Ib9b5fa5d91e3e25438e282d6aee1e71d927d1bb0

I added a new pair of functions to compare fuzzy comparisons to a new
header for math utilities. The motivation for using a separate header
was to be able to use templates and inline header functions for utility
functionality currently spread across multiple tests.

I moved the fuzzy compare out of TestMatrix3x3 for now, but would like
to move this out of other tests without impacting their performance. I
also took the opportunity to migrate the test to use vtkNew and added in
the missing copyright header.

This commit ensures that a chart is removed from the scene if it will no
longer be part of the chart matrix.

Change-Id: I0e7c7065aa836f9372b5143e8adeac211ce7d9f8

Still need to get the histograms in the diagonal, and handle layout
issues. Also handled the case where the input is being set to null. This
may require some special handling to remove all charts.

Change-Id: Ie5c71cd730fe7fe08432c0f861a35824a3d59f1b

Takes a vtkTable as input, sets up the charts and displays them. Still
more work to get everything lined up correctly, only showing scatter
plots in the bottom triangle and histograms in the diagonal.

This class provides a matrix of charts where the width and the height
can be set. It takes care of instantiating the charts, and setting their
size to occupy individual elements in the matrix.

0fb32e54 Force the opengl buffer to be fully refreshed.
8a679e20 Fix QVTKWidget refresh on resize problem on Windows

A hack in QWidgetPrivate::repaint_sys (qbackingstore.cpp) checks the type
of the widget QPaintEngine. If it is an OpenGL engine, it then forces the
 repaint to be done on the entire widget instead of the dirty region.

Changing the paint engine type, ensures QVTKWidget to be fully repainted on Windows when resizing the widget.
This fix makes the behavior of QVTKWidget similar to QVTKWidget2.
It has visible results when the flag Qt::WA_PaintOnScreen is set on Windows (not the case because of the previous commit)

Change-Id: I5ce944d73c5931ca9423b9cc848bc1ede6bf5b91

When resizing a toplevel QVTKWidget, only the newly exposed part is refreshed, not the entire viewport.

Qt::WA_PaintOnScreen is only supported on X11:
http://doc.qt.nokia.com/4.7/qt.html#WidgetAttribute-enum

For all purpose widgets, it is ok to leave the flag Qt::WA_PaintOnScreen for other platforms, because the flag is ignored.
See QWidget::setAttribute(), there is a special to ignore the flag on Windows.
However, QVTKWidget uses a custom QPaintEngine, so the hack done in QWidget::paintEngine() on Windows is not applied and
doesn't ignore the flag then:
Here is an extract from qwidget_win.cpp (in QWidget::paintEngine)
    // We set this bit which is checked in setAttribute for
    // Qt::WA_PaintOnScreen. We do this to allow these two scenarios:
    //
    // 1. Users accidentally set Qt::WA_PaintOnScreen on X and port to
    // windows which would mean suddenly their widgets stop working.
    //
    // 2. Users set paint on screen and subclass paintEngine() to
    // return 0, in which case we have a "hole" in the backingstore
    // allowing use of GDI or DirectX directly.
    //
    // 1 is WRONG, but to minimize silent failures, we have set this
    // bit to ignore the setAttribute call. 2. needs to be
    // supported because its our only means of embeddeding native
    // graphics stuff.
    const_cast<QWidgetPrivate *>(d_func())->noPaintOnScreen = 1;

Please note that QVTKWidget2 (QGLWidget) sets the flag Qt::WA_PaintOnScreen all platforms.
However, various hacks in Qt GUI (qwidget.cpp, qwidget_win.cpp, qbackingstore.cpp...) make QGLWidget works fine on Windows.
