Subject: [PATCH] [usdImagingGL] fix thresholds for testUsdImagingGLPurpose

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.
