I'm not sure I understand exactly what you are saying there, but I
don't think it's from using the wrong PangoLayout function.

gdk_draw_layout() is probably what you want. It just renders a layout
to a GdkDrawable. gtk_paint_layout() renders a themed layout, using
a widget's style. So themes can override what gtk_paint_layout() does.
