title: Which is the equivalent of the StringToColor function for a TAlphaColor?
body: <p>I'm looking for the equivalent to the <a href="http://docwiki.embarcadero.com/VCL/en/Graphics.StringToColor" rel="nofollow"><code>Graphics.StringToColor</code></a> function to convert 
  a string to an <code>TAlphaColor</code> (Color type used by Firemonkey). I searched in the <a href="http://docwiki.embarcadero.com/RADStudio/en/" rel="nofollow">online Rad Studio help</a> as well as in the related firemokey units without luck :(. I can write easily a function to convert these values but I prefear use a RTL function. Anybody knows if exist any function to convert a String to a TAlphaColor in delphi-xe2?</p>
