void MythOpenGLPainter::DrawRect	(	QRect	Area,

overridevirtual

Draw a rectangle.

If it is a simple rectangle, then use our own shaders for rendering (which saves texture memory but may not be as accurate as Qt rendering) otherwise fallback to Qt painting to a QImage, which is uploaded as a texture.

Note: If high DPI scaling is in use, just use Qt painting rather than handling all of the adjustments required for pen width etc etc.
