Coordinate system in screen coordinates?

Jun 6, 2010 at 10:44 PM


I've been using this library, tweaking it to my needs a bit, and it seems that it might assume typical 2D screen coordinates (top left is 0,0, increasing Y is "lower" or "south").  Is this true?  I'm using a standard coordinate system (up is +y, down is -y), so am I correct that I will need to modify this class to get things to work this way?
