This is a bad way to go about it. Most themes are per widget dependent,
so you will really want a widget class/name parameter to send with it
otherwise you will usually be wrong, or better yet, a specific style its
being grabbed from. And this doesn't belong in cairo but in the gtk
side, via a get value. 

gtk_style_get_color_as_rgb(style, "base",GTK_STATE_NORMAL, &r, &g, &b);
cairo_set_rgb(r, g, b);

also be wary this will not work unless the theme in question SETS all
the colors, which many pixmap themes do not, in those cases this will
almost always result in black.

similar issue to the above, you would use the style to get the pango
font description and convert to set on cairo.
