Method IsWindowNavFocusable

include/imgui/imgui.cpp:14435–14438

Can we focus this window with Ctrl+Tab (or PadMenu + PadFocusPrev/PadFocusNext) Note that NoNavFocus makes the window not reachable with Ctrl+Tab but it can still be focused with mouse or programmatically. If you want a window to never be focused, you may use the e.g. NoInputs flag.
