Gimp/app/composite/make-gimp-composite-dispatch.py
Helvetix Victorinox d3fc41f0c2 regenerated new code taking advantage of simplified function prototypes. 
* app/composite/gimp-composite-dispatch.[ch]: regenerated new code
taking advantage of simplified function prototypes.

* app/composite/gimp-composite-test.c: New regression testing
driver.  This file is automatically generated, but it's included
in the cvs tree for expediency.

* app/composite/ns.py: hopeful checks for which OS is currently
running as a hint to what nm(1) is available.

* app/composite/gimp-composite-mmx.[ch]
* app/composite/gimp-composite-sse.[ch]
* app/composite/gimp-composite-generic.[ch]: function prototype
cleanup.

* app/composite/make-gimp-composite-dispatch.py: generates code to
test compositing functions.

* app/composite/gimp-composite-regression.[ch]: support for
automatically testing compositing functions.

# This programme creates C code for gluing a collection of compositing
# functions into an array indexed by compositing function, and the
# pixel formats of its arguments.
#
# I make some assuptions about the names of the compositing functions.
#
# I look into the namespace of a set of object files and figure out
# from them what compositing functions are implemented. This let's me
# build a table with the right cells populated with either the special
# compositing functions, or to use a generically implemented
# compositing function.
# These are in the same order as they appear in the
# ./app/base/base-enums.h GimpLayerModeEffects enumeration, because we
# (probably unwisely) use the value of the enumeration as an index
# into the Big Table.
#
# XXX I'd like some python functions that let me rummage around in C code....
