want_capture_keyboardOverride io.WantCaptureKeyboard on the next frame; this does not itself consume OS events.
Override io.WantCaptureKeyboard flag next frame (said flag is left for your application to handle, typically when true it instructs your app to ignore inputs).
e.g. force capture keyboard when your widget is being hovered.
This is equivalent to setting "io.WantCaptureKeyboard = want_capture_keyboard"; after the next NewFrame() call.
Override keyboard input capture for the next frame.
