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
