* extract_pose_from_pose only checked one of the list items for NULL when looping over them yet its possible they are different sizes. * game_free_pose needed to be used rather then MEM_freeN, channels would never be freed leaking memory. * setChannel() would make a new pose that wasnt aligned with the existing pose, the lists are assumed aligned so when extracting the channels its unlikely this was ever useful. * Added getChannel() - returns pose loc/size/quat * Added option args for setChannel(channel, matrix) or setChannel(channel, loc, size, quat)
