gdk_pixbuf_loader_write and short files

["Matthias Clasen" <matthiasc poet de>]

The pixbuf loader interface has problems with small images.
If the complete image file is shorter than 

#define LOADER_HEADER_SIZE 128

than load_increment is never called by gdk_pixbuf_loader_write
and consequently, the pixbuf is not created. To see this problem in
action, run gtk+/demos/testpixbuf on the appended pbm file.

I admit that images this small are rapidly becoming extinct in this
world of multi-megabyte machines, but we could still try to handle them
correctly.
