* Painter.h:

Browse Source 
* Painter: new ctor that sets drawing_enabled_ to true.
  * setDrawingEnabled(), isDrawingEnabled(): new methods.

* QLPainter.C: only draw if drawing is enabled.

* nullpainter.h: deleted.

* rawpainter.C::paintPar(): only draw if we are inside the Paragraph.

* InsetTabular::draw(): use new Painter method instead of a NullPainter.

* InsetMathNest::drawSelection(): ditto.
