Sim/graphics/view/panel render type
This should read:
How to draw the panel? 0=2-d or 3-d unlit panel, 1=3-d, non-lit, 2=3-d, lit
Ben describes this dataref as: '0 really means "2-d or 3-d drawn in one single lit + unlit pass" - the draw type tells you what kind of LIGHTING is going on (lit, unlit, both) - it does NOT tell you whether the 2-d or 3-d panel is being drawn.'
