  This function extracts a TMeshImage type from the passed raster, using transparent
  pixels to identify the mesh boundary.

  The returned mesh image has coordinates in the original raster reference (ie origin at
  the lower-left image corner, pixel metric)

  \warning The resulting mesh image has <B> no dpi <\B>. Users \b must set it manually after
           this function has been invoked.
