Hi, Phil.
New CR were filed:

JDK-8059941 [D3D] The fix for JDK-8029253 should be ported to d3d pipeline
JDK-8059943 [macosx] Aqua LaF should use BI.TYPE_INT_ARGB_PRE for a 
better performance
JDK-8059944 [OGL] Metrics for a method choice copying of texture should 
be improved
JDK-8059942 Default implementation of DrawImage.renderImageXform() 
should be improved for d3d/ogl
