[OpenJDK 2D-Dev] [9] RFR JDK-6601097:Margins are not reset to hardware margins when width/height is 0 or -ve alongwith x, y

[prasanta sadhukhan]

Hi All,

Please review a fix for jdk9 which is a continuation of the fix of 
JDK-6543815.

Bug: https://bugs.openjdk.java.net/browse/JDK-6601097
webrev: http://cr.openjdk.java.net/~psadhukhan/6601097/webrev.00/

6543815 fix resets the x,y to 0 if they are negative before creating a 
MediaPrintableArea and the platform replaces it with hardware margins 
when printing.
This works only if x/y is negative.
But, If either width/height is negative alongwith x or y, then the 
margin is set to the java def 1 inch margin and not hardware margins.

This is because width/height -ve results in IAE in MediaPrintableArea 
constructor and so values are ignored.
Added a check for -ve width/height to make sure width/height are set to 
minimum paper width/height.

Regards
Prasanta
