// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2024-05-07: Removed silent return when calling ImGui_ImplWin32_WndProcHandler() with no active context! If you don't always have an active context, check that ImGui::GetCurrentContext() != nullptr before calling this.
// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys, app back/forward keys.
// 2023-09-25: Inputs: Synthesize key-down event on key-up for VK_SNAPSHOT / ImGuiKey_PrintScreen as Windows doesn't emit it (same behavior as GLFW/SDL).
// 2023-09-07: Inputs: Added support for keyboard codepage conversion for when application is compiled in MBCS mode and using a non-Unicode window.
