You'll need to convert your 8-bit gray image to a 8-bit RGBA image
(create a pixbuf of the right size, use gdk_pixbuf_get_pixels(),
and just write into the data correctly taking into account
gdk_pixbuf_get_rowstride().) Then use gdk_pixbuf_render_to_drawable()
to draw that.
There is no support for single-channel pixbufs in gdk-pixbuf or
GDK currently.
