From d0566bc26fcf6ca396118701fa11900b627f2c09 Mon Sep 17 00:00:00 2001 From: Mathias Agopian Date: Thu, 17 Nov 2011 17:49:17 -0800 Subject: Add support for sending VSYNC events to the framework use gui/DisplayEvent to receive the events. Events are dispatched through a unix pipe, so the API is compatible with utils/Looper. see gui/DisplayEvent.h for more info.
