The problem is that the gdk-pixbuf library doesn't provide a function
that takes inline data in the original XPM format, i.e. the whole
declaration.  See [1].

variable declarations -- so if you have them *in* your program, you're
going to use the thus declared variables.  If you don't have them *in*
your program, there's only one other alternative: you have separate
files.  So gdk-pixbuf only provides two kinds of functions: ones that
operate on files and ones that take the *content* of variables declared
in XPM files.
