Make camera() parameters optional
Make camera() parameters optional

The documentation for camera() suggests that all 9 parameters are optional, but passing some - but not all - does break currently. This proposed change lets you call camera() with three parameters for changing only the camera position, or six parameters for camera position & target (without having to specify the not-so-intuitive up vector also). Shouldn't affect current behavior inadvertently (e.g. when calling camera() w/o params).
