Use lower resolution bitmap for tests

The test file decompresses to about 48 MB, which can cause an
`OutOfMemoryError` on lower end devices.

Also, a test appears to apply a rotation to this bitmap without downscaling
first, leading to exceeding a maximum texture width/height of 4096 on some
devices.

Replace the test file with one that has a quarter of the original's
width/height so that these tests can pass reliably even on lower end
devices.
