AnchorPane's measurement and layout calculations are not correct when pixel-snapping is enabled. The following problems are fixed in this PR:
* Stretched sizes and right/bottom positions are not snapped: `computeChildWidth`/`computeChildHeight` subtract anchors and insets from raw `getWidth()`/`getHeight()`, while `layoutChildren()` passes those values directly to `resizeRelocate`. * Content-biased measurement and layout use different dependent dimensions: `computeWidth()` passes `fillHeight=false`, while layout eventually uses `fillHeight=true` * Result of snapped calculations is not re-snapped. * Anchors use `snapPositionX/Y`. However, anchors are empty space and should use `snapSpaceX/Y`. --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - fix - tests Changes: https://git.openjdk.org/jfx/pull/2264/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=2264&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8390608 Stats: 442 lines in 2 files changed: 360 ins; 11 del; 71 mod Patch: https://git.openjdk.org/jfx/pull/2264.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/2264/head:pull/2264 PR: https://git.openjdk.org/jfx/pull/2264
