  * Remember, both U and V are individually of size w/2*h/2, but they are interleaved.
  * The layout looks like this :

/**
* It took me a whole 6 hours to finally get the color conversion right.
* I have a fairly good understanding of the various color formats (YUV420P, SP, 422, etc etc), 
* and how to access individual Y, U, and V components.
* I however struggled because of a very simple yet hair-pulling gotcha. 
* All primitives in Java are signed! If you come from a Python-like world where 0xFF prints 255, 
* you see yourself struggle just the same. I am however embarrassed at spending 6 hours on this.
