From aa8cea953dc66bcf4cb4d08f2681f9e6cb1bc8c5 Mon Sep 17 00:00:00 2001 From: Pauli Nieminen Date: Thu, 30 Dec 2010 19:19:32 +0200 Subject: render: Don't filter 0 return from GetTimeInMillis In animate cursor block handler code assumes GetTimeInMillis returns always nonzero value. This isn't true when time wraps around. To prevent any problems in case GetTimeInMillis would return zero use activeDevice variable to track if we have received time.
