// As can be seen from av1_get_palette_color_index_context(), the possible
// contexts are (2,0,0), (2,2,1), (3,2,0), (4,1,0), (5,0,0). These are mapped to
// a value from 0 to 4 using 'palette_color_index_context_lookup' table.

// Palette Y mode context for a block is determined by number of neighboring
// blocks (top and/or left) using a palette for Y plane. So, possible Y mode'
// context values are:
// 0 if neither left nor top block uses palette for Y plane,
// 1 if exactly one of left or top block uses palette for Y plane, and
// 2 if both left and top blocks use palette for Y plane.
