All those apps you've been telling us about.

If allocated drawing buffer size < canvas size < MAX_VIEWPORT_DIM then an application using canvas{Width,Height} to set the viewport will end up with only part of its intended view visible in the canvas.

If allocated drawing buffer size >= MAX_VIEWPORT_DIM < canvas size then pixel based features based on hard-coded pixel numbers will be larger than the developer intended, relative to everything else, because there are fewer pixels than expected.
