Set the font and font properties.
Parameters
----------
font_dict : dict
A dict of keyword parameters to be passed to
:class:`matplotlib.font_manager.FontProperties`.
Possible keys include:
* family - The font family. Can be serif, sans-serif, cursive,
'fantasy', or 'monospace'.
* style - The font style. Either normal, italic or oblique.
* color - A valid color string like 'r', 'g', 'red', 'cobalt',
and 'orange'.
* variant - Either normal or small-caps.
* size - Either a relative value of xx-small, x-small, small,
medium, large, x-large, xx-large or an absolute font size, e.g. 12
* stretch - A numeric value in the range 0-1000 or one of
ultra-condensed, extra-condensed, condensed, semi-condensed,
normal, semi-expanded, expanded, extra-expanded or ultra-expanded
* weight - A numeric value in the range 0-1000 or one of ultralight,
light, normal, regular, book, medium, roman, semibold, demibold,
demi, bold, heavy, extra bold, or black
See the matplotlib font manager API documentation for more details.
http://matplotlib.org/api/font_manager_api.html
Notes
-----
Mathtext axis labels will only obey the `size` and `color` keyword.
Examples
--------
This sets the font to be 24-pt, blue, sans-serif, italic, and
bold-face.
>>> prof = ProfilePlot(ds.all_data(), 'density', 'temperature')
>>> slc.set_font({'family':'sans-serif', 'style':'italic',
