The draw functions inside the DrawScreenspace class (and some functions from other classes like "DrawText.WriteScreenspace()") have overloads that don't specify the camera whose screenspace should be used for drawing. When drawing with these overloads then the default behaviour is that an automatic camera search happens in the background. Instead of this automatic search this "defaultCameraForDrawing" value can be assgined. It will then be used instead of the automtic search.
