[Bf-committers] Modifier stack refactor

[Ben Batt]

Hi again,
Thanks for the input, everyone. It looks like it'd be better to wait
until after 2.47 and then commit to trunk, since it's kind of a pain
to merge changes from modifier.c to individual modifier files (I know,
I've been doing it :-) ). I'm tracking it in git here, so I should be
able to keep it up to date with trunk ok.

Yeah, it's been due for a while :-)

Headers aren't needed for the individual modifiers, as the interface
for each modifier is defined in a ModifierTypeInfo structure in the
MOD_modifiername.c file. These structures are declared extern in
blender/source/blender/modifiers/MOD_modifiertypes.h so that the
modifier stack can access them. This is very similar to the way the
nodes API works.

Yes, these could possibly be moved over as well, I need to look into
that a bit further.

Thanks,
