[Piglit] [PATCH 00/21] Tests for ARB_internalformat_query2 extension

[Alejandro Piñeiro]

This series provides the tests for the ARB_internalformat_query2
extension:

https://www.opengl.org/registry/specs/ARB/internalformat_query2.txt

The corresponding bug is being tracked at:

https://bugs.freedesktop.org/show_bug.cgi?id=92687

The difference with the RFC series that I sent at the beginning of the
week is that adds proper dependency checking and some minor
cleanups. I already marked as superseeded that series on patchwork.

Notes:

 * It used arb_internalformat_query tests as a base.

 * The first commit removes the references to
   ARB_internalformat_query2 on the ARB_internalformat_query
   tests. query2 not only expands the possible attribute values
   GetInternalformativ can receive, but also changes its behaviour, so
   we concluded that it would be better to keep both test suites
   independent.

 * common.c defines a test_data structure, which main purpose is
   to abstract the fact that we have now two really similar methods
   (GetInternalformativ and GetInternalformati64v) which only
   difference is the type of the params parameter. So the tests would
   not worry about castings or which specific method is being
   called. One could argue that at this point it deserves a C++ class,
   but we preferred to stick to C.

 * For several pnames there aren't too much to test, because after
   all, we are talking about an specification that returns values that
   depend on the current implementation/hw. For that reason several
   pnames are handled by a generic test (generic-pname-checks) that
   only ensures that the returned values are among the possible values
   defined by the spec, or the defined unsupported response if that is
   the case.

 * The dependencies are being managed somewhat different that in other
   extensions. In most extensions, the dependencies with other
   extensions are a "hard" dependency, so one given extension is
   needed for a different extension. With ARB_internalformat_query2 we
   have "soft" dependencies, in the sense that there are dependencies
   with other extensions, but lacking those dependencies doesn't
   prevent query2 to be supported, but just affects the returned value
   for some pnames. For example:

     "Dependencies on EXT_texture_sRGB

       If EXT_texture_sRGB or equivalent functionality is not
       supported, queries for the SRGB_READ <pname> and for sRGB
       internalformats return the appropriate "unsupported" response."

   So in most cases, if some dependency is not fullfilled, instead of
   skipping, it checks that it returns the unsupported response
   defined for that pname.

 * All the 13 tests passes with the patch series that was proposed
   this week for Mesa [1]. They were also run against NVIDIA
   proprietary drivers (NVIDIA GeForce GTX 950 - NVIDIA 352.55). In
   that case, the pass/fail ratio is 5/8. What is failing is explained
   on the commit message.

cheers,
Alejandro (on behalf of the team that worked on this)
