// PushDisabled()/PopDisabled()
// - Those are not yet exposed in imgui.h because we are unsure of how to alter the style in a way that works for everyone.
// We may rework this. Hypothetically, a future styling system may set a flag which make widgets use different colors.
// - Feedback welcome at https://github.com/ocornut/imgui/issues/211
// - You may trivially implement your own variation of this if needed.
// Here we test (CurrentItemFlags & ImGuiItemFlags_Disabled) to allow nested PushDisabled() calls.
