Hi Alistair,

some nitpicking...

Please use the "d3dx9:" prefix for this and the other patches.

I think this is usually done as "*out =
&animation->ID3DXAnimationController_iface" or similar (where
"animation" is the result of
impl_from_ID3DXAnimationController(iface)).

Similarly this is usually written in a slightly different way. Please
follow the style of the other (recent) QueryInterface implementations,
we are pretty consistent now and it would be nice to preserve that
consistency.

Can this (and the other instances of it in the patch) simply use
"double" instead? Apparently the only difference between the two is
that DOUBLE sometimes forces alignment to 8 bytes. That should only
matter for struct fields though, as far as we are concerned, so we
should probably prefer plain double.

It doesn't really matter but this comment is unnecessary.

Please use the usual "lowercase and underscores" style for the parameter names.
Also check the '*' placement a couple of lines below.
