// This is IconFamily's designated initializer. It creates a new IconFamily that initially has no elements.
//
// The proper way to do this is to simply allocate a zero-sized handle (not to be confused with an empty handle) and assign it to hIconFamily. This technique works on Mac OS X 10.2 as well as on 10.0.x and 10.1.x. Our previous technique of allocating an IconFamily struct with a resourceSize of 0 no longer works as of Mac OS X 10.2.
