// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2026-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2026-04-16: Made ImGui_ImplSDL2_GetContentScaleForWindow(), ImGui_ImplSDL2_GetContentScaleForDisplay() helpers return a minimum of 1.0f, as some Linux setup seems to report <1.0f value and this breaks scaling border size. (#9369)
// 2026-03-09: [Docking] Fixed an issue dated 2025/04/09 (1.92 WIP) where a refactor+merge caused ImGuiBackendFlags_HasMouseHoveredViewport to never be set, causing foreign windows to be ignored when deciding of hovered viewport. (#9284)
// 2026-02-13: Inputs: systems other than X11 are back to starting mouse capture on mouse down (reverts 2025-02-26 change). Only X11 requires waiting for a drag by default (not ideal, but a better default for X11 users). Added ImGui_ImplSDL2_SetMouseCaptureMode() for X11 debugger users. (#3650, #6410, #9235)
// 2026-01-15: Changed GetClipboardText() handler to return nullptr on error aka clipboard contents is not text. Consistent with other backends. (#9168)
