  // Provide optimized functions to convert images from 8bits yuv420 to rgb24 format
  
  // There are a few slightly different variations of the YCbCr color space with different parameters that 
  // change the conversion matrix.
  // The three most common YCbCr color space, defined by BT.601, BT.709 and JPEG standard are implemented here.
  // See the respective standards for details
  // The matrix values used are derived from http://www.equasys.de/colorconversion.html
  
  // YUV420 is stored as three separate channels, with U and V (Cb and Cr) subsampled by a 2 factor
  // For conversion from yuv to rgb, no interpolation is done, and the same UV value are used for 4 rgb pixels. This 
  // is suboptimal for image quality, but by far the fastest method.
  
  // For all methods, width and height should be even, if not, the last row/column of the result image won't be affected.
  // For sse methods, if the width if not divisable by 32, the last (width%32) pixels of each line won't be affected.
