title: Translating X,Y Coordinate
body: <p>I currently have a user control that contains items that have a certain X, Y coordinate and there are limits to what those points must be within.  In this case those positions are 0 > X > 40 and 0 > Y > 80 (40x80).  The control I am hosting those items in is dynamic but has a certain aspect ratio based on window size.  I need to translate those X &amp; Y coordinates into relative locations within the user control.  Any help is greatly apprecaited!  Thanks in advance!  If it matters/helps, I'm using Silverlight.</p>
