[XaraXtreme-dev] Fix for BZ 1269

[Martin Wuerthner <lists@xxxxxxxxxxxxxxx>]

Find attached below a fix for BZ 1269. Ironically, this is what the 
code looked like initially, but in a last minute change I decided to 
use UserRect::Translate to improve readability. I did not realize that 
that routine would check whether the coordinates make sense (which 
they don't because only one half of each coord is actually used).
