// An input method for linux that does absolutely no translation.

// The current InputMethodMinimal makes assumptions that a system will only
// input/output keydown/keyup events; it assumes that things don't work like
// Windows does. When it gets a keydown event, it then tries to insert a
// character at the same time.
//
// However, we're standardizing on Windows' WM_CHAR style events. This tries to
// follow InputMethodWin::DispatchKeyEvent() instead, because PlatformViewX11
// now synthesizes a character events so that we have one behaviour across our
// platforms.
