while that certainly works for most cases it falls apart when dealing with postfx where it's an unnamed array of variable types of inputs. shifted the profile assignment to #define INIT_IMAGEASSET_ARRAY(name, profile, index) so there's still a really obvious point where you can see the default setting, even if it's not in the more desireable OG definition spot for postfx in particular, given we can swap that, provided an example of how to do just that
