       Get a property value of a font. The mfont_get_prop() function gets the value of key property of font
       font.  key must be one of the following symbols:

       Mfoundry, Mfamily, Mweight, Mstyle, Mstretch, Madstyle, Mregistry, Msize, Mresolution, Mspacing.

       If font is a return value of mfont_find(), key can also be one of the following symbols:

       Mfont_ascent, Mfont_descent, Mmax_advance.

           If key is Mfoundry, Mfamily, Mweight, Mstyle, Mstretch, Madstyle, Mregistry, or Mspacing, this
           function returns the corresponding value as a symbol. If the font does not have key property, it
           returns Mnil. If key is Msize, Mresolution, Mfont_ascent, Mfont_descent, or Mmax_advance, this
           function returns the corresponding value as an integer. If the font does not have key property, it
           returns 0. If key is something else, it returns NULL and assigns an error code to the external
           variable merror_code.
