SandWiched Lighting and Bitmap Hijacker Class

Further progress on Matt's lighting tool.
The lighting system has been abstracted in 
a way that allows me to extract the 
plasma and lumen layers and draw
them at different times.

Now need to put in the SAVE feature for this.

After that... 
I have 2 more controls I want to 
add to our preset controller:
1: Alpha of bombs sprites control.
2: Alpha of tilemap control


How will I do this?
I will make a bitmapHijacker class.
It will hijack a bitmap reference, 
and make an INTERNAL UNALTERED copy of it.

THEN it will use the 
INTERNAL UNALTERED copy 
as a template used to 
ALTER the original hijacked bitmap.
