crashed when doing fast url switching (see here): fixed by blocking until internal used CEF browser object (used by each slice of a renderer) is created.
crashed when decreasing the width/height inputs (see here): fixed by doing an intersect for each dirty rectangle reported by cef before writing to the texture.
crashed when setting new "Update DOM" pin to true: should be fixed by new blocking behaviour in constructor.
fixed various issues in CefXmlReader (used to translate CefDom to XDocument/XElement).
MIDI module fixes
normalised MidiNoteOut, MidiControllerOut, MidiProgramOut to consistently use channels 0-15 on pins.
fixed incorrect channel mappings.
resetting the channel pin does not result in setting a value of 0.5.
