If you want to make sure that your program follows this recommended
practise, you can define the preprocessor symbols GTK_DISABLE_SINGLE_INCLUDES
and GDK_PIXBUF_DISABLE_SINGLE_INCLUDES to make GTK+ generate an error

There are some exceptions: <filename>gdkkeysyms.h</filename> is not included in
<filename>gdk.h</filename> because the file is quite large; see

<filename>gdkx.h</filename> must be included independently because It's
platform-specific; see
