Currently, testUsdImagingGLPurpose relies solely on perceptual diff, which fails to detect a change between world_0.png (which shows a sphere) and world_1.png (which is empty). Changing to a reasonable default for pixel difference (-fail .1, -failpercent 10) which can successfully distinguish the two images.
