// notification. If a 32-bit window has been subclassed by a 16-bit app,
// WOW needs to copy the notify structure into 16-bit space, and then when
// the 16-bit guy does a CallWindowProc(), they have to copy it back into
// 32-bit space. Without the size information, you fault on the
// 32-bit side because the notify structure is incomplete.
//
// Some notifications have multiple structures associated with them, in
// which case you should return the largest possible valid structure.
