figure: facecolor not respected (Agg backend) ?

Hi, i am using the example with the Agg or

    > WXAgg backends. If i insert the following line:
    > rcParams["figure.facecolor"] = "r" the background is red when
    > using the WXAgg driver but with the Agg backend the
    > background of the png image is still white.

    > Any hints ? (matplotlib 0.64, linux)


The default figure facecolor is passed as a kwarg in savefig. The
idea is that you often want a different background color for the
figure in a GUI (eg gray) and in hardcopy (eg white)

  savefig('myfile', facecolor='r')

should work.
