/*
Looks up @key in the list of options that may have been attached to the
@pixbuf when it was loaded, or that may have been attached by another
function using gdk_pixbuf_set_option().

For instance, the ANI loader provides "Title" and "Artist" options.
The ICO, XBM, and XPM loaders provide "x_hot" and "y_hot" hot-spot
options for cursor definitions. The PNG loader provides the tEXt ancillary
chunk key/value pairs as options. Since 2.12, the TIFF and JPEG loaders
return an "orientation" option string that corresponds to the embedded
TIFF/Exif orientation tag (if present).
