// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2024-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2024-10-07: OpenGL: Changed default texture sampler to Clamp instead of Repeat/Wrap.
// 2024-06-28: OpenGL: ImGui_ImplOpenGL3_NewFrame() recreates font texture if it has been destroyed by ImGui_ImplOpenGL3_DestroyFontsTexture(). (#7748)
// 2024-05-07: OpenGL: Update loader for Linux to support EGL/GLVND. (#7562)
// 2024-04-16: OpenGL: Detect ES3 contexts on desktop based on version string, to e.g. avoid calling glPolygonMode() on them. (#7447)
