Actually these tests will fail, because level == 5 is passed in instead of 0.
More work needs to be put in to get the tests working.

To answer your other question about testing ES3, this is actually a good test
for the ES3 case. You only need to change GLES2DecoderTest1 to GLES3DecoderTest
and put it in gles2_cmd_decoder_unittest_framebuffers.cc
