Maybe I'm answering my own questions at this point but for "line" drawing modes, the coordinates would need to indicate the center of the pixel to land exactly and thus would be at 0.5,0.5 for the 0,0 pixel.

It appears that there is a default translation of (-0.5f, -0.5f). Resetting the graphics does not seem to set things back to the identity either. Here i...
