Hi, I didn't check all the patch in detail, but as Illia is saying, it
is correct to pass TEXTURE_BUFFER to GetInternalFormat*. I also disagree
that this case it is not tested, or at least for the case I checked. See
below, I have two extra comments.

Not sure if this is really needed, as we have texture_targets, defined
on common.h too, that is valid_targets except TEXTURE_BUFFER and
RENDERBUFFER. The latter also need some special handling.

Your point is that TEXTURE_BUFFER shouldn't be tested here. But it is
tested in the sense that for this specific pname, querying should return
GL_NONE.

C&P the comment at try_local:
/* From the spec:
 *
 * "- IMAGE_FORMAT_COMPATIBILITY_TYPE: The matching criteria use for
 *   the resource when used as an image textures is returned in
 *   <params>. This is equivalent to calling GetTexParameter with
 *   <value> set to IMAGE_FORMAT_COMPATIBILITY_TYPE. Possible values
 *   are IMAGE_FORMAT_COMPATIBILITY_BY_SIZE or
 *   IMAGE_FORMAT_COMPATIBILITY_BY_CLASS.  If the resource is not
 *   supported for image textures, or if image textures are not
 *   supported, NONE is returned."
 *
 * So try_local is equivalent to try_basic, except that instead of
 * checking against a list of possible value, we test against the
 * value returned by GetTexParameter, or against GL_NONE if not
 * supported of if it is not a texture.
 */
 
So in this case, TBO is tested (or should be, unless a bug on the test),
but the test is just to confirm that we get a GL_NONE. On the code is
checked against texture_targets. As it doesn't belong there, it is not
used  glGetTexParameteriv  and just checks if GL_NONE is returned.

I still need to check the other cases though.
