Question related to this one, except I need the same for the Graphics.
Lets say I have the following drawings:
Graphics[{
Line[{ Q, P, V }] ,
Arrow[{P, P + v }] ,
Arrow[{P, P + vx }] ,
Arrow[{P, P + vy}] ,
{Dashed,
Line[{Q + (dir1*d1), P + v, V + (dir2*d2)}]
},
FontSize -> 16, Background -> RGBColor[1, 1, 1, 1],
Text["Q", Q],
Text["P", P],
Text["V", V],
}, Axes -> True]
But on my drawing sysytem (this drawing should illustrate part of it work), the screen coordinates goes from top to bottom (in reverse order). So I want to reverse it somehow.
