Subject: Introduce QRasterWindow

A simple convenience class providing a QWindow that has a
paintEvent and supports opening a painter on itself. It
behaves exactly like QOpenGLWindow in this respect, which is not
surprising since they share the same base class (QPaintDeviceWindow).

QRasterWindow does not however have any OpenGL dependencies and will
be present in -no-opengl builds too.

[ChangeLog] Added QRasterWindow, a thin convenience wrapper for a
QWindow on which a QPainter can be opened.
