This PR is a follow up of [JDK-8199592](https://bugs.openjdk.java.net/browse/JDK-8199592).
When using DPI scaling levels > 1, labels of controls get truncated when they are added to Dialogs which have an owner Window. To fix the issue, this PR binds dialog and owner window renderScale X, Y properties. It also provides a system test that can be tested on Linux and Windows. Before applying the fix, the `Check` text of the checkboxes is rendered as `Che...`. With the fix, the test verifies, for a given UI scale, that the rendered text is `Check` when launching the dialog. ------------- Commit messages: - Bind dialog and owner window renderScale properties, including test Changes: https://git.openjdk.java.net/jfx/pull/369/files Webrev: https://webrevs.openjdk.java.net/?repo=jfx&pr=369&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8258592 Stats: 130 lines in 2 files changed: 130 ins; 0 del; 0 mod Patch: https://git.openjdk.java.net/jfx/pull/369.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/369/head:pull/369 PR: https://git.openjdk.java.net/jfx/pull/369
