This class handles drawing and updating the status pane, which contains the number of lives, health, and score the player has.
Draw() will cause the whole status pane to be rendered, Update() will only render what has changed since the last Draw()/Update(). If Update() is called and no previous Draw()/Update() has occured the whole pane will be rendered.
The status area is defined by the status section of the level file. This is a series of TUint16s these are:
first background sprites to be drawn when pane is first rendered: 1,offset to sprite,x size, ysize, x pos, ypos .... this list is terminated with a 0xffff
then the health status area: health sprite offset, sprite x size, sprite y size, background color, then a list of locations to draw the sprite x,y, x,y, ... terminated with 0xffff if the players health level is one then only the first location will be filled, two the first and second locations, etc. If the players health is greater that the number of locations then all locations are filled.
then there is the lives status area, this is the same format as the health status area.
then there is the location to draw the players score xpos, ypox, foreground color, background color.
then there is an alignment TInt16 if it is required to align to a 32 bit word boundary.
finally there is sprite data refered to by the offsets above. Sprite offsets are all from the start of the status data.

Open a status panel. This opens the RScreenUtils and remebers the status data. This does not plot the status pane on the screen.

Update status pane. Just update the bits that have changed by erasing or plotting more status sprites and erasing and replotting the score if it has changed.

Redraw the whole status pane. Just resets the saved data to -1 and calls Update().

Update a sprite status section. This updates either the health or the lives depending on the position in the status data. The update is done by either plotting more sprites or erasing old ones.
