[OpenJDK 2D-Dev] [9]: RFR JDK-8023213 [macosx] closed/java/awt/FontClass/NaNTransform.java fails on MacOS X 10.9

[prasanta sadhukhan]

Hello All,

Please review a fix for jdk9

Bug: https://bugs.openjdk.java.net/browse/JDK-8023213
webrev: http://cr.openjdk.java.net/~psadhukhan/8023213/webrev.00/

drawString takes long time in mac native call 
CGContextShowGlyphsAtPoint() if NaN transform is used which translated 
to x & y being NaN.
Fix is to prevent calling mac api for such invalid usage.

Regards
Prasanta
