// The following array specifies the initial dot-correction data for the
// TLC5940 output channels.  0 disables all output on that channel, 63 means
// that maximum output is allowed.  There should be as many entries as there
// are TLC5940 output channels (i.e. NUM_TLCS * 16).  The first entry is
// channel 0.
