From 75d38ef1ed100bbb2883e242f4c87fbab3dd0617 Mon Sep 17 00:00:00 2001 From: Alexandros Frantzis Date: Wed, 27 Sep 2017 15:09:13 +0300 Subject: [PATCH] timeline: Add GPU timestamp timepoint argument The purpose of this argument is to hold timestamp information about events that occurred on the GPU. This argument allows us to include GPU timestamps in timepoints such as the beginning and end of frame rendering.
