RFR: 8015854: [macosx] JButton's HTML ImageView adding unwanted padding

Damon:

Sorry for joining this chat late. Is the core problem here that Swing is 
positioning graphic elements incorrectly -- and those bad positions are 
platform-independent?

If so: this might be a good candidate for me to try to rewrite a test to 
avoid the Robot class. I have a Graphics2D implementation 
<https://github.com/mickleness/pumpernickel/blob/master/src/main/java/com/pump/graphics/vector/VectorGraphics2D.java> 
that catalogs rendering operations. If just the act of reviewing those 
catalogued instructions can detect the underlying problem: this might be 
a simpler/faster alternative. (I’m assuming tests written using the 
Robot class are more expensive to run and more brittle.)

Does this sound like something that might benefit this test case? (I can 
have a look at it in a few days.)

Regards,
