android_hardware_qcom_display/liboverlay/overlayLib.h
Naomi Luis 8afdc162ea Upgrades to the updateOverlay functionality. 
Update the overlay when we have a channel up. Previously, we did updates
only when the width and height changed. Now, we always update the overlay
when the channel is open, and not close the channel to update parameters
such as orientation change, flags etc.
