Subject: [PATCH] vo_gpu: interpolation-threshold check allow any integer

Instead of checking whether the ideal_frame_duration to vsync_interval ratio is approximately 1.0, check whether the ratio is approximately an integer. This way, any video whose fps is approximately a factor of the display Hz will pass the check.
