 Context:[[BR]]
 While georeferencing multiple maps with a simple linear transformation.

 How to reproduce:[[BR]]
  * Using the plug-in, georeference a first image (for ex. map1.png).[[BR]]
  * When completed, open an unrelated image (for ex. map2.png), and answer
 "No" when asking if existing points have to be saved. [[BR]]
  * Define enough points for the georeferencing. [[BR]]
  * Click on "Start georeferencing". A dialog warns that the image already
 contains georeferencing data, which is not the case. It is a confusion
 with the previously georeferenced image. The warning proposes either to
 overwrite the world file or to cancel.

 Workaround: [[BR]]
  * Go into "Transformation settings". It show you the same parameters as
 for the previous georeferencing. [[BR]]
  * Just click OK, the parameters will be reapplied, with the current image
 path being considered. [[BR]]

 Although the workaround is simple, the behavior is a bit strange. When not
 paying enough attention on the warning message, some existing data would
 be overwritten.
