[OpenJDK 2D-Dev] Review Request for bug (JDK-8039345) Strange behaviour of per-pixel translucency on linux

[prasanta sadhukhan]

Hi,

Please review a fix for this issue:
8039345 Strange behaviour of per-pixel translucency on linux

Bug description: https://bugs.openjdk.java.net/browse/JDK-8039345
webrev: http://cr.openjdk.java.net/~serb/prasanta/8039345/webrev.00/

Note: A wrong (PictStandardRGB24) picture format was used for xrendering 
even for surface having alpha support thereby neglecting the alpha 
transparency. It should be using PictStandardARGB32 or TRANSLUCENT 
picture format for correct alpha support in xrendered surface.

Regards
Prasanta
