// 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_ImplOpenGL2_NewFrame() recreates font texture if it has been destroyed by ImGui_ImplOpenGL2_DestroyFontsTexture(). (#7748)
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
// 2021-12-08: OpenGL: Fixed mishandling of the ImDrawCmd::IdxOffset field! This is an old bug but it never had an effect until some internal rendering changes in 1.86.
