From: Gregory Hainaut <gregory.hainaut at gmail.com>
Check the pipeline object state creation. glGenProgramPipelines only
reserves the names. The object does not "exist" until it is bound.
Also take the opportunity to test negative value on
glGenProgramPipelines and glDeleteProgramPipelines.
This test fails on AMD's closed-source driver (Catalyst 13.4 on
HD5770). The test crashes when -1 is passed to glGenProgramPipelines.
They are presumably treating the GLsizei as unsigned and generating a
lot of names. They also return GL_TRUE from glIsProgramPipeline
before the object has been bound.
This test fails on NVIDIA's closed-source driver (unknown version on
GTX 650). The test crashes in glGetProgramPipelineiv for a pipeline
that has never been bound. They are presumably dereferencing a NULL
pointer in some internal data structure. They also return GL_TRUE
from glIsProgramPipeline before the object has been bound.
V4: split the new test in a separate commit
V5 (idr):
* Use 'pass = foo() && pass;' idiom instead of 'pass &= foo();'. C's
short-circuit evaulation rules cause these to be different.
* s/GLboolean/bool/g
* Produce no output with -auto.
* Add test to CMakeLists.gl.txt.
* Trivial reformatting.
