public interface ILspGLState
ILspGLStatesets up the OpenGL state of a
ILcdGLDrawable. This can include, for instance, the current color, texture, line width and so on. When more than one state object is used, the setup/cleanup methods should be called in a LIFO order: the last state that has been set up should be the first one to be cleaned up.
