Should expose ConnectorType/SignalFormat properties for RANDR 1.3
Submitted by Federico Mena Quintero

RANDR 1.3 specifies mandatory properties for outputs, ConnectorType and SignalFormat. However, the Intel driver doesn't expose these properties.
ConnectorType is the only robust way in which clients can detect the built-in display in laptops (where ConnectorType=Panel). Currently clients must resort to heuristics like "is the output name LVDS, Lvds, LCD, etc.?".
