- * these r, g an b values are then passed thru a table lookup to take the
- * gamma curve into account and find the corresponding pixel value.
- *
- * the table must store more than 3*256 values because of the possibility

- * -176 to 255+176 for red
- * -133 to 255+133 for green
- * -222 to 255+222 for blue
- *
- * If the input y,u,v values are right, the r,g,b results are not expected
- * to move out of the 0 to 255 interval but who knows what will happen in
- * real use...
- *
- * the red, green and blue conversion tables are stored in a single 1935-entry
- * array. The respective positions of each component in the array have been
