That might be the solution! (but you loose some contrast)

Another problem with scaling is the thickness of lines. Example: you  
are (or a control) drawing lines on a form with a thickness of 1 pixel. 
If you scale the form from 96 to 192 dpi what to do with the thickness 
of lines? It should be 2 pixels on a 192 dpi screen to get the same 
thickness.
