1.31 -Returns the pointer to the table of 16-bit normalisation table.
1.32 -The table is currently used for performing un-multiplying Premultiplied Alpha color channels.
1.33 -Use: Let x be c * a/255, and y = c, then y = (x/a)*255, where a is in 0-255 range.
1.34 - To use this table, use y = (x * Table[a])>>8. i.e, the inaccurate division is converted
1.35 - to more accurate multiplication and shift.
