| * \brief Base class for testing invariance of entire primitive set |

| * Draws two patches with identical tessellation levels and compares the |
| * results. Repeats the same with other programs that are only different |
| * in irrelevant ways; compares the results between these two programs. |
| * Also potentially compares to results produced by different tessellation |
| * levels (see e.g. invariance rule #6). |
| * Furthermore, repeats the above with multiple different tessellation |
| * value sets. |
| * |
| * The manner of primitive set comparison is defined by subclass. E.g. |
| * case for invariance rule #1 tests that same vertices come out, in same |
| * order; rule #5 only requires that the same triangles are output, but |
| * not necessarily in the same order. |

| //! These tests correspond to dEQP-GLES31.functional.tessellation.invariance.* |
| //! Original OpenGL ES tests used transform feedback to get vertices in primitive order. To emulate this behavior we have to use geometry shader, |
| //! which allows us to intercept verticess of final output primitives. This can't be done with tessellation shaders alone as number and order of |
| //! invocation is undefined. |
