Bad push for JDK-8230728: Thin stroked shapes are not rendered if affine transform has flip bit

[Lindenmaier, Goetz]

Hi Laurent, 

please open a JBS Issue 
  'Backout "8230728: Thin stroked shapes are not rendered if affine transform has flip bit" from jdk11u'
and send a RFR with the backout change. Tag it as jdk11u-critical-request.

Also, I see crashes in our tests that were triggered by your
push. I didn't investigate, but they are in the fonts area.

The following jtreg tests crashed on AIX:
javax/swing/Headless/HeadlessJMenuBar.java 	
javax/swing/Headless/HeadlessJSlider.java 	
javax/swing/Headless/HeadlessJTextArea.java 	
javax/swing/Headless/HeadlessJToolBar_Separator.java 	
javax/swing/Headless/HeadlessJToolBar.java

So maybe we should investigate this before pushing to jdk11u-dev.

Best regards,
  Goetz.
