unsafePreservingMatrix :: IO a -> IO a
OpenGL Graphics.Rendering.OpenGL.GL.CoordTrans
A more efficient, but potentially dangerous version of preservingMatrix: The given action is not allowed to throw an exception or change the current matrix mode permanently.
unsafeRenderPrimitive :: PrimitiveMode -> IO a -> IO a
OpenGL Graphics.Rendering.OpenGL.GL.BeginEnd
A more efficient, but potentially dangerous version of renderPrimitive: The given action is not allowed to throw an exception.
