Rotates <text> by <angle> (degrees anti-clockwise by default). The optional argument <option list> is a comma-separated list of any of the following options:
The number of units in one full anti-clockwise rotation. So units=-360 means that <angle> specifies degrees clockwise whereas units=6.283185 means that <angle> is in radians.
The point of rotation. The value <label> may contain one from either or both of the two lists: lrc (left, right, centre) and tbB (top, bottom, baseline). Alternatively the origin may be specified using the following two keys:
Scales <text> by <h scale> in both directions if <v scale> omitted, otherwise scales <text> by <h scale> horizontally and <y scale> vertically.
Scales <text> so that it is <h length> wide and <v length> high. To preserve the aspect ratio, use ! instead of one of the dimensions.
