GUIUtility.GUIToScreenPoint
static function GUIToScreenPoint(guiPoint: Vector2): Vector2;
Description

Convert a point from GUI position to screen space.

Note: In Unity the screen space y coordinate varies from zero at the top edge of the window to a maximum at the bottom edge of the window. This is different from what you might expect.
