Havoc Pennington 1a0a5d0399 New function to create a blank pixbuf.
1999-10-27  Havoc Pennington  <hp@pobox.com>

* src/gdk-pixbuf.c (gdk_pixbuf_new): New function to create a
blank pixbuf.

* src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Check all
three progressive load funcs are non-NULL, rather than checking
begin_load three times. Also, check whether begin_load returns
NULL on failure.
