[Piglit] [PATCH] new test : glsl-max-vertex-attrib.c

[tapani.palli at intel.com]

From: Tapani Pälli <tapani.palli at intel.com>

Queries the value for GL_MAX_VERTEX_ATTRIBS and uses that as index
to set a value with various functions. GL specification states that
GL_INVALID_VALUE should occur if index >= GL_MAX_VERTEX_ATTRIBS.

Refactored (no shader needed for this) and cleaned up the code + added
missing copyright header.
