<Swing Dev> [8] Review request for 7156657 Version 7 doesn't support translucent popup menus against a translucent window

[Pavel Porvatov]

Hello,

Please review a fix for the following issue:
   7156657 Version 7 doesn't support translucent popup menus against a 
translucent window
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7156657

The webrev is here: http://cr.openjdk.java.net/~rupashka/7156657/ 
<http://cr.openjdk.java.net/%7Erupashka/7156657/>

The fix of CR 7027486 (JPopupMenu doesn't take window shape into 
account, http://hg.openjdk.java.net/jdk8/awt/jdk/rev/9024198193ce) 
doesn't take into account that some users use translucent windows with 
translucent menus. After discussions the following decision was made:
1. When JPopupMenu#setLightWeightPopupEnabled is set to false 
HEAVY_WEIGHT popups is used (instead of MEDIUM_WEIGHT). This fix was 
done in CR 6800513 (GTK-LaF renders menus incompletely, 
http://hg.openjdk.java.net/jdk8/awt/jdk/rev/cd00d68e06ac and 
http://hg.openjdk.java.net/jdk8/awt/jdk/rev/8800a98316b2) and that 
allows to use non-translucent and non-clipped popups for translucent or 
shaped windows
2. Fix of CR 7027486 should be reverted
3. The TransparentRuler should be corrected according new fix

Regards,
Pavel.
