/** Implementation of Group 3. Test description follows:
 *
 * 1. Make sure that GL_REFERENCED_BY_GEOMETRY_SHADER_EXT property works
 *    correctly for all supported interfaces.
 *
 *    Category: API.
 *
 *    1. Create a program object with boilerplate fragment and vertex shaders,
 *       as well as an attached geometry shader using all of the features,
 *       properties of which can later be examined using
 *       glGetProgramResourceiv() call.
 *    2. Link the program object.
 *    3. Use GetProgramResourceiv() calls to verify values reported for
 *       geometry stage are as expected.
