struct swf_kerning {
	if(f_font2_wide) {
		unsigned short		f_kerning_code1;

	else {

		unsigned char		f_kerning_code2;
	signed short		f_kerning_adjustment;

The following table defines the number of TWIPs to move left or right before to draw the 2nd character when the 1st one was drawn right before it. For instance, the letters AV may be drawn really close so the V is written over the A. To the contrary, WI may be seperated some more so the I doesn't get merged to the top of the W.

The computation to move the drawing pen is done as follow:

  /* writing 'AV' */
  x += f_font2_advance['A'] + f_kerning['AV'].f_kerning_adjustment;

where 'x' is the position at which f_kerning_code1 was draw.
