Right now we have PRIM_HEALTH to track an object's hit points and it works nicely.
Now I want to track object hit points in a HUD external to the object and display with a health bar and show the values. For that I need to read the maximum health value of an object with PRIM_HEALTH, but I don't know the maximum health of it.
PRIM_MAX_HEALTH would make this easy.
Without it I'm using a workaround of assuming PRIM_HEALTH is already a percentage instead of an absolute value and trusting objects set their PRIM_HEALTH to said percentage instead of an absolute value, which works for now, but is not ideal.
