handle = pango.FontMap([fonttype])
A fontmap is used to cache information about available fonts, and holds certain global parameters such as the resolution. In most cases, you can use pango.GetDefaultFontMap() instead.
Note that the type of the returned object will depend
on the particular font backend Cairo was compiled to use;
alternatively, you can also pass the optional fonttype argument
to explicitly specify a backend to use. See cfontface:GetType()
for a list of font types.
This function returns the newly allocated Pango font map, which should be freed with pfontmap:Free().
