Kerning pairs for the font. Kerning pair adjust the spacing between two characters.
Each string consist of three space separated values: "from" string, "to" string and integer offset. Each combination form the two string for a kerning pair, e.g, [code]ab cd -3[/code] will create kerning pairs [code]ac[/code], [code]ad[/code], [code]bc[/code], and [code]bd[/code] with offset [code]-3[/code].
