Detailed Description

Control buffering the sending of commands to ds9;
annoying but necessary for anything resembling performance

The usual usage pattern (from a module importing this file, ds9.py) is:

    with ds9.Buffering():
        # bunches of ds9.{dot,line} commands
        ds9.flush()
        # bunches more ds9.{dot,line} commands
