options. (#2587, broken in 1.69 by #2384).
- CollapsingHeader: Better clipping when a close button is enabled and it overlaps the label. (#600)
- Scrollbar: Very minor bounding box adjustment to cope with various border size.
- Nav: Fixed gamepad/keyboard moving of window affecting contents size incorrectly, sometimes leading
to scrollbars appearing during the movement.
- Style: Added style.WindowMenuButtonPosition (left/right, defaults to ImGuiDir_Left) to move the
collapsing/docking button to the other side of the title bar.
- Style: Made window close button cross slightly smaller.
