In particular,
- We need to link against gdk_pixbuf-2.0 in addition to
gdk_pixbuf_xlib-2.0.
- The header gdk-pixbuf-xlib.h has been moved to the gdk-pixbuf-xlib
directory.
- The function gdk_pixbuf_new_from_file now requires two arguments.
- We need to define GdkColor ourselves since we don't include gdk.h.
Inspired by a patch by Nerijus Baliunas [1].

In particular,
- Remove option to compile with deprecated GDK-PixBuf 1.0.
- Remove *ROOT variables; libdockapp should be in the default include search
path and X11R6 directories are deprecated.
- Remove /opt/gtk2/bin from PIXBUF_CFG; pkg-config is likely elsewhere.
- Remove CPPFLAGS from CFLAGS and INCDIRS and DEFINES from CFLAGS; we don't
want these to disappear if user defines different flags.
Inspired in part by similar patches in Gentoo [1] and by Nerijus Baliunas [2].
