#
# 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....
