Add documentation about how to use Type-1 fonts in graphics

[ppurka]

See this ask.sagemath thread.

The default matplotlib behavior is to use Type-3 fonts in graphics. However, some (many?) publications have a strict stipulation of using Type-1 fonts only in the document. The method to force matplotlib to have this behavior is to add a matplotlibrc file in the working directory with the following contents:

rcParams['ps.useafm'] = True
rcParams['pdf.use14corefonts'] = True
rcParams['text.usetex'] = True

This tidbit should be added to the main graphics documentation in some nice way. A ..note maybe?
