Status bar face hysteresis

When the player's health moves between ranges corresponding to different status bar face animations, the red HEALTH percentage changes immediately, but the status bar face is not updated until the end of the current animation sequence.

For example, if a severely injured player (below 20% health) gains a new weapon, followed closely by a large health pickup such as a megasphere, the status bar briefly displays a very high health percentage alongside an extremely bloodied face, as shown in the figure.

There is also the ouch face bug. The ouch face was ment to appear whenever the player lost more that 20 points of health during an attack. However, due to a programming error the ouch face is only seen when the player gains 20 points of health in an attack, making it very rare. You can see the ouch face if you do something like get hit with a fireball at the same time you pick up a health kit.
