[Piglit] [PATCH 08/10] arb_separate_shader_objects: add unused location qualified input test
New tests to check that an unused input varying, which would be matched based on its explicit location, won't cause a link failure if there is no matching output variable. From the ARB_separate_shader_objects spec v.25: " * An output variable is considered to match an input variable in the subequent shader if: * the two variables match in name, type, and qualification; or * the two variables are declared with the same location layout qualifier and match in type and qualification." ... " For program objects containing multiple shaders, LinkProgram will check for mismatches on interfaces between shader stages in the program being linked and generate a link error if a mismatch is detected. A link error will be generated if any statically referenced input variable or block does not have a matching output."
