* Scaled, normalized, rounded and tweaked to yield RGB 565:
* |R| |74 0 101| |Y' - 16| >> 9
* |G| = |74 -24 -51| |Cb - 128| >> 8
* |B| |74 128 0| |Cr - 128| >> 9
*
* Converts two lines from YUV to RGB565 and writes to LCD at once. First loop
* loads Cb/Cr, calculates the chroma offset and saves them to buffer. Within
* the second loop these chroma offset are reloaded from buffer. Within each
* loop two pixels are calculated and written to LCD.
