matplotlibrc

I have my matplotlibrc file tweaked to use nicer default colors for my plots. PyPlot does not seem to be reading matplotlibrc and instead uses the normal defaults. Is there a way to read matplotlibrc? If so then it could be used to select the backend as well (as long as MacOSX is supported for Mac).

Start by tracing how PyPlot initializes matplotlib and whether it loads the user's matplotlibrc configuration. Check how backend selection is handled, including MacOSX support, and verify that customized default colors and backend settings are applied when the issue is resolved.
