WIP: Additional stylable properties support for ImageView

[aalmiray]

Relates to #29. Intended as a the start of discussion as not all properties (viewport, x, y still missing) have been added as stylable.

@andres can you target this PR to develop branch (instead of master)? That way, appveyor might pass. Also, can you comment on the suggestions from @svenreimers

[aalmiray]

Yes, I’ll rebase the PR with develop and apply the suggestion by @svenreimers. Give me 1 day and it’ll be done :smile:

[svenreimers]

Will we need an update on the css reference document as well?

[aalmiray]

@svenreimers yes, absolutely.

[abhinayagarwal]

Is this PR waiting for an update on the css reference document?

[kevinrushforth]

No, this issue never got to the point where it is ready for code review. There are API design issues that would need to be hammered out first, such as whether we should add more styleable properties for nodes such as ImageView; if so, which attributes; how it interacts with layout.

[aalmiray]

@kevinrushforth should the discussion be moved to the mailing list?

As announced in this message, the official jfx repository is moving from hg.openjdk.java.net/openjfx/jfx-dev/rt to github.com/openjdk/jfx.

This sandbox repository is being retired on 1-Oct-2019. You will need to migrate your WIP pull request to the openjdk/jfx repo if you want to continue working on it. Here are instructions for migrating your pull request. The updated CONTRIBUTING.md doc has additional information on how to proceed.

Once you have done this, it would be helpful to add a comment with a pointer to the new PR.
