+ GenericTransformation.InWorldSpace (Merges the object transformation and the last master transformation) + Ray class for Raycasting (may not work correctly) + Util.CallGarbageCollector() can call the garbage collector. + GLWindow.WindowFlags allow to easly switch between Window <-> Borderless Window (this will cause the window to fill the entire screen) <-> Exclusive Fullscreen. ~ Made the bloom-texture scale a constructor-parameter. SM.OGL: + OpenGL-GarbageCollector integration. + BoundingBox.GetBounds(Matrix4, out Vector3,out Vector3) allows for easy transformation of the bounding box. + GLObjects can now marked as not compiled. Where it always returns false at WasCompiled. SM2D: ~ Improved the Mouse2D.MouseOver Algorithm.
