This patch adds a "size" parameter, which scales the filter radius
according to movie diagonal, the unit being percent of diagonal.
This makes the effect far more predictable across movies of different
resolutions.
Usage example (with possibly useless values):
-vf gradfun=strength=1.2:size=2.3
Based on a patch by Radosław Szkodziński <astralstorm@gmail.com>
This fixes two of the following warnings on non-x86 machines:
libmpcodecs/vf_gradfun.c:388:5: warning: "HAVE_EBX_AVAILABLE" is not defined

Neither the asm() nor the __asm__() keyword is part of the C99
standard, but while GCC accepts the former in C89 syntax, it is not
accepted in C99 unless GNU extensions are turned on (with -fasm).
The latter form is accepted in any syntax as an extension (without
requiring further command-line options).
Sun Studio C99 compiler also does not accept asm() while accepting
__asm__(), albeit reporting warnings that it's not valid C99 syntax.

This avoids clashes with fcntl.h under certain circumstances.
