[PATCH] 8160325: Provide a public API to obtain the FXCanvas for an embedded scene.

[Kevin Rushforth]

I got the attachment, since Alexander also CCed me directly. I will 
attach it shortly.

I do have two comments on this:

1) We are past Feature Freeze, so all Enhancements need formal JDK 9 
R-team approval [1][2]. In this case, the justification can be internal 
API that is no longer accessible in JDK 9 due to Jigsaw (I would be very 
reluctant to consider any other Enhancement request this late in the 
process), but I will need to look at it and then take it through the 
approval process, provided that I feel it is in scope.

2) Some of the changes you list seem unrelated to this enhancement and 
are better done as separate issues (e.g., the rework of the 
SWTCursorsTest). Also, I am unconvinced of the need to force GTK 2; in 
fact it seems at odds with the work we have done with JEP 283 [3].
