/** A fragment shader to convert NV12 to RGB.
  * Input textures Y - is a block of size w*h. 
  * texture UV is of size w*h/2. 
  * Remember, both U and V are individually of size w/2*h/2, but they are interleaved.
  * The layout looks like this :
  * ----------
  * |        |
  * |   Y    | size = w*h
  * |        |

// Some helpers for converting GPS readings from the WGS84 geodetic system to a local North-East-Up cartesian axis.

// The implementation here is according to the paper:
// "Conversion of Geodetic coordinates to the Local Tangent Plane" Version 2.01.
// "The basic reference for this paper is J.Farrell & M.Barth 'The Global Positioning System & Inertial Navigation'"
