\class QGenericMatrix
\brief The QGenericMatrix class is a template class that represents a NxM transformation matrix with N columns and M rows.
\since 4.6
\ingroup painting
\ingroup painting-3D
The QGenericMatrix template has four parameters:
\table
\row \i N \i Number of columns.
\row \i M \i Number of rows.
\row \i T \i Element type that is visible to users of the class.
\row \i InnerT \i Element type that is used inside the class.
\endtable
Normally T and InnerT are the same type; e.g. float or double.
But they can be different if the user wants to store elements
internally in a fixed-point format for the underlying hardware.
\sa QMatrix4x4
