| * \brief Verify fractional spacing conditions for a single line |
| * |
| * Verify that the splitting of an edge (resulting from e.g. an isoline |
| * with outer levels { 1.0, tessLevel }) with a given fractional spacing |
| * mode fulfills certain conditions given in the spec. |
| * |
| * Note that some conditions can't be checked from just one line |
| * (specifically, that the additional segment decreases monotonically |
| * length and the requirement that the additional segments be placed |
| * identically for identical values of clamped level). |
| * |
| * Therefore, the function stores some values to additionalSegmentLengthDst |
| * and additionalSegmentLocationDst that can later be given to |
| * verifyFractionalSpacingMultiple(). A negative value in length means that |
| * no additional segments are present, i.e. there's just one segment. |
| * A negative value in location means that the value wasn't determinable, |
| * i.e. all segments had same length. |

| * \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. |

| * \brief Case testing user-defined IO between TCS and TES |
| * |
| * TCS outputs various values to TES, including aggregates. The outputs |
| * can be per-patch or per-vertex, and if per-vertex, they can also be in |
| * an IO block. Per-vertex input array size can be left implicit (i.e. |
| * inputArray[]) or explicit either by gl_MaxPatchVertices or an integer |
| * literal whose value is queried from GL. |
| * |
| * The values output are generated in TCS and verified in TES against |
| * similarly generated values. In case a verification of a value fails, the |
| * index of the invalid value is output with TF. |
| * As a sanity check, also the rendering result is verified (against pre- |
| * rendered reference). |
