Corruption in scrolled text example

[elan]

Scrolling text can leave garbage in-between characters. This is due to the code here:

    for (uint8_t i=0; i<=charWidth; i++)
    {
      mx.transform(MD_MAX72XX::TSL);
      if (i < charWidth)
        mx.setColumn(0, cBuf[i]);
      delay(DELAYTIME);
    }

The correct code should be like this (we need to zero out the row explicitly):

    for (uint8_t i=0; i<=charWidth; i++)
    {
      mx.transform(MD_MAX72XX::TSL);
      mx.setColumn(0, (i < charWidth) ? cBuf[i] : 0);
      delay(DELAYTIME);
    }

Thanks for a great library!
