According to the OpenGL 3.2 Core Profile specification, section 3.8.12:
"For one-, two-, and three-dimensional and one-and two-dimensional array
textures, a texture is mipmap complete if all of the following
conditions hold true:
- [...]
- levelbase <= levelmax [...]
Using the preceding definitions, a texture is complete unless any of
the following conditions hold true:
- [...]
- The minification filter requires a mipmap (is neither NEAREST nor
LINEAR), and the texture is not mipmap complete."
(This text also appears in all GL >= 3.2 specs and the ES 3.0 spec.)
From this, we see that levelbase <= levelmax should only affect mipmap
completeness, not base-level completeness.
Prior versions of GL did not have the notion of mipmap completeness,
simply calling the texture incomplete in this case. But I don't think
we really care.
Fixes es3conform's sgis_texture_lod_basic_completeness test.
