// 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.
// 2022-11-09: OpenGL: Reverted use of glBufferSubData(), too many corruptions issues + old issues seemingly can't be reproed with Intel drivers nowadays (revert 2021-12-15 and 2022-05-23 changes).
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
// 2022-09-27: OpenGL: Added ability to '#define IMGUI_IMPL_OPENGL_DEBUG'.
// 2022-05-23: OpenGL: Reworking 2021-12-15 "Using buffer orphaning" so it only happens on Intel GPU, seems to cause problems otherwise. (#4468, #4825, #4832, #5127).

// During 2021 we attempted to switch from glBufferData() to orphaning+glBufferSubData() following reports
// of leaks on Intel GPU when using multi-viewports on Windows.

// - The idea is that instead of "eating" a given input, we can link to an owner id.

// - Input queries can then read input by specifying ImGuiKeyOwner_Any (== 0), ImGuiKeyOwner_None (== -1) or a custom ID.
// - Legacy input queries (without specifying an owner or _Any or _None) are equivalent to using ImGuiKeyOwner_Any (== 0).

// - SetItemKeyOwner() is a shortcut for common simple case. A custom widget will probably want to call SetKeyOwner() multiple times directly based on its interaction state.
