PgColor.parseWithAlpha

Fill in the fields of a color from a string specification.

The string can either one of a large set of standard names. (Taken from the CSS Color specification, or it can be a hexadecimal value in the form #rgb, #rrggbb, #rrrgggbbb or #rrrrggggbbbb where r, g and b are hex digits of the red, green, and blue components of the color, respectively. (White in the four forms is #fff, #ffffff, #fffffffff and #ffffffffffff.)

Additionally, parse strings of the form #rgba, #rrggbbaa, #rrrrggggbbbbaaaa, if @alpha is not %NULL, and set @alpha to the value specified by the hex digits for a. If no alpha component is found in @spec, @alpha is set to 0xffff (for a solid color).
