How to draw a thin line?

A line along an integer coordinate will be anti-aliased and thus two pixels wide. You could probably call g.drawLine(0.5f, 0.5f, w+0.5f, 0.5f) (not sure whether it has to be +0.5 or -0.5). Also there is Graphics::drawHorizontalLine/Graphics::drawVerticalLine. The top and left lines aren’t two pixels because they are clipped by the grapics context. There is also a Graphics::drawRectangle available. Chris

I remember that @fabian explained it somewhere else a bit more detailed, but I don’t find that post ATM.
