libfpx header not self contained

[nros]

fpxlib.h in libfpx does use size_t but does not include this type.
compiling a program like:
#include <fpxlib.h>
int main(){return 0;}

breaks with messages about size_t missing.

including stddef.h fixes this.
a patch is available at:

We applied your patch to libfpx-1.3.1-9, available by sometime tomorrow. Thanks.

Thanks.

Also related to libfpx is that the pdf files in the doc directory are broken. I can't read them with any pdf reader I tested. Just to point it out.
