    - PangoFonts class is placed in the shared space and it uses the 
X11GraphicsDevice from the unix space. Could there be problems with 
build compilation on platforms differ from Unix?
   - It is better to rename the scale field to nativeScale just to not 
mix it with other scale types
   - Does the test test/java/awt/font/FontScaling/FontScalingTest.java  
fails without the proposed fix on Linux?

   Thanks,
   Alexandr.
