How about adding a 'count' parameter, to convert a buffer of values? It
could be quite a bit quicker for largish images.

void
gdk_colorspace_convert (gdouble *src_values,
                        GdkColorspace src_format,
                        gdouble *dest_values,
                        GdkColorspace dest_format,
			int pixel_count);

Hope I've not misunderstood.
