The Library Reference says "PushMatrix evacuates the rotation matrix to the stack", but which rotation matrix? PushMatrix/PopMatrix take no arguments and this leaves me a little confused. I've also noticed that some of the Matrix functions say that "the rotation matrix is fragmented" - whatever that means. I'm guessing that the two things are related, and that PushMatrix and PopMatrix are used to save and restore the rotation matrix which gets "fragmented". Am I right? Either way, could someone explain. Thanks, Herbs
