****************************************

[RECT] Rectangle
			[5] nBits
			[nBits float] X
			[nBits float] Y
			[nBits float] WIDTH 
			[nBits float] HEIGHT

* int - (+-) first bit determines positive or negative
* float - int (+-) divided by 32, used to convert stored ints to floats
* point - [float,float] x,y pair
* fARGB is FlippedA,R,G,B format (A is flipped so no alpha has fewer bits in normal cases)
