> > WebMIDI API guarantees that MIDIInput::onmessage is called back with a single MIDI message. To guarantee this, this CL introduces MIDIMessageQueue class, which allows you to
> > - maintain fragmented MIDI message.
> > - Skip any invalid data sequence.
> > - Reorder MIDI messages so that "System Real Time Message", which can be inserted at any point of the byte stream, can be placed at the boundary of complete MIDI messages.
> > - (Optional) Reconstruct complete MIDI messages from data stream that is compressed with "running status".
> >
> > This CL also replaces existing System Exclusive message validation logic in MIDIHost::OnSendData with MIDIHost::IsValidWebMIDIData, which can detect SysEx message even when it is concatenated with non-SysEx messages.
> >
> > With this change, renderer/blink can be much simpler and free from this kind of data validation.
