< 0.0 tilted left.
skewfac is the fraction of the character height by which the top of the character is shifted with respect to the bottom.
skew() is used to slant characters to give them more impact or to create an italic appearance. Skewing of characters is turned on and off by inserting the character ` (back apostrophe or grave sign) within a string. ` acts as a toggle switch. Its special meaning is overridden by preceding it with an @.
