Header reorganization. (#51999, Jeff Franks, reorganization
proposed by Havoc Pennington)
* gdk-pixbuf.h: This is now an include-only header, and the only
one which applications should directly use.
* gdk-pixbuf-animation.h: Add animation api from gdk-pixbuf.h.
* gdk-pixbuf-io.h: Add io api from gdk-pixbuf.h.
* gdk-pixbuf-loader.h: Add loader api from gdk-pixbuf.h.
* gdk-pixbuf-transform.h: New header.
* gdk-pixbuf-core.h: New header.
Sat Jun 19 01:44:12 2004 Matthias Clasen <maclas@gmx.de>
* gdk-pixbuf-scale.c (gdk_pixbuf_composite): Add a figure which
