<pre>dEQP-GLES2.functional.texture.specification.basic_copytexsubimage2d.2d_alpha
The test sticks some data in via glTexImage2D (into each level), then renders a
gradient to a FB, and then runs glCopyTexSubImage to overwrite part of each
level's data with the new data. It appears that the first 32 pixels of level0
are good, but the next 32, which have the partial copy over them, were
improperly initialized. Like a load was missing?</pre>
