// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2023-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2023-04-18: OpenGL: Restore front and back polygon mode separately when supported by context. (#6333)
// 2023-03-23: OpenGL: Properly restoring "no shader program bound" if it was the case prior to running the rendering function. (#6267, #6220, #6224)
// 2023-03-15: OpenGL: Fixed GL loader crash when GL_VERSION returns NULL. (#6154, #4445, #3530)
// 2023-03-06: OpenGL: Fixed restoration of a potentially deleted OpenGL program, by calling glIsProgram(). (#6220, #6224)
