// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2022-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2023-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
// 2021-12-08: OpenGL: Fixed mishandling of the the ImDrawCmd::IdxOffset field! This is an old bug but it never had an effect until some internal rendering changes in 1.86.
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
// 2021-05-19: OpenGL: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
