// 2023-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.

- Popups: clarified meaning of 'p_open != NULL' in BeginPopupModal() + set back user value

- Drag and Drop: Rework drop target highlight: reduce rectangle to its visible portion, and
then expand slightly. A full rectangle is always visible and it may protrude slightly. (#4281, #3272)
- Drag and Drop: Fixed submitting a tooltip from drop target location when using AcceptDragDropPayload()
with ImGuiDragDropFlags_AcceptNoPreviewTooltip and submitting a tooltip manually.

- Tables: Fixed an edge-case when no columns are visible + table scrollbar is visible + user
- Tables:
- Added angled headers support. You need to set ImGuiTableColumnFlags_AngledHeader on selected
columns and call TableAngledHeadersRow(). Added style.TableAngledHeadersAngle style option.
- Added ImGuiTableFlags_HighlightHoveredColumn flag, currently highlighting column header.
- Fixed an edge-case when no columns are visible + table scrollbar is visible + user

clipper it would have asserted. Without a clipper, the scrollbar range would be wrong.
