Description
Whilst investigating a JavaFX issue with gradient paint not being printed,
I noticed that even after my fix there, it was still not working on Mac.
It turns out that printing of LinearGradientPaint and RadialGradientPaint
have been broken on Mac, probably forever .. at least since Oracle
started shipping a JDK for OS X.

Attached test GradientPrintTest.java and resulting PDF show this.

This is a must-fix for 9 and needs an 8u backport. If it needs to be a P2 it can be ..

LinearGradientPaint printing is not effected because in QuartzSurfaceData.m#CompleteCGContext contextTexturePath() is commented out. http://hg.openjdk.java.net/jdk9/client/jdk/file/ccc7d013fd4e/src/java.desktop/macosx/native/libawt_lwawt/awt/QuartzSurfaceData.m#l1083 For normal gradientPaint, CompleteCGContext() is called with renderType = SD_Shade which calls contextGradientPath() which works ok. whereas for lineargradientpaint, CompleteCGContext() is called with renderType = SD_Pattern If we uncomment contextTexturePath(), there is a crash in ImageSurfaceData.m#LockImage when it tries to access isdo->javaImageInfo[sun_java2d_OSXOffScreenSurfaceData_kImageStolenIndex]

It would be good to attempt at least a LinearGradientPaint fix in 9...

This has actually been reported before. See https://bugs.openjdk.java.net/browse/JDK-8080134 which mentions TexturePaint and LinearGradientPaint but not RadialGradientPaint. That was closed as a dup. of https://bugs.openjdk.java.net/browse/JDK-8040635 which was originally only about TexturePaint The fixes may not be different depending on what we can do through Quartz so I will keep this one open. Also this came up again in FX printing : https://bugs.openjdk.java.net/browse/JDK-8142394

Definetly fails on JDK7u - I reproduced on 7u40. It did work in Apple JDK 6u65 however .. I don't see in the Quartz code used for printing anything that looks like an explicit handling of these cases. gradients are handled but that seems like it may be for GradientPaint. So this may need some new code to be written.
