Sets the color for drawing, filling, or both. The colorspace should
be one of 'gray', 'rgb, 'cmyk', 'spot', 'pattern'. Depending on the
colorspace either
only the first, the first three or all parameters will be used.
The parameter type can be 'both', 'fill',
or 'fillstroke'.
Bugs
The second parameter is currently not always evaluated. The color is
sometimes set for filling and drawing just as if 'fillstroke' where
passed.
