Refine the drawing of the health bar with pip transparency fade

[TaranDahl]

Extended health bar drawing logic

• In vanilla, the algorithm used for drawing the health bar is very crude, with problems of insufficient accuracy and incorrect boundary handling.
• You can now enable a new way of drawing the health bar through the following flag.
  • The new logic will draw the last pip of the health bar with a transparency fade.

In rulesmd.ini:

[AudioVisual]
ExtendedHealthBarDrawing=false  ; boolean
