Makes the OpenGL state that is represented by this rendering context current with the wxGLCanvas {\it win}.
Note that {\it win} can be a different wxGLCanvas window than the one that was passed to the constructor of this rendering context.
If { \it RC } is an object of type wxGLContext, the statements {\it RC.SetCurrent(win);} and {\it win.SetCurrent(RC);} are equivalent,
