//|                                                                  |

//|  These are ordinary globals rather than #define, because quality |
//|  is something an application legitimately changes AT RUNTIME:    |
//|  full quality for a panel that is drawn once and then sits       |
//|  there, draft quality while the user is dragging something with  |
//|  the mouse and forty frames a second matter more than a perfect  |
//|  edge.                                                           |

//| The rasterizer computes coverage ANALYTICALLY in X - exact       |
//| fractional overlap, no sampling at all - but SAMPLES in Y. This  |
//| value is therefore the VERTICAL anti-aliasing quality, and the   |
//| cost of a fill is very close to linear in it.                    |
//|                                                                  |
//|   1  no vertical AA. Vertical and horizontal edges are still     |
//|      perfect - they always were - but a shallow diagonal shows   |
//|      banding, because the shape's height within a row is being   |
//|      guessed from one sample.                                    |
//|   2  most of the improvement, for half the price of 4.           |
//|   4  the default, and the point of diminishing returns on screen.|
//|   8  visibly better only on near-horizontal edges of large       |
//|      shapes.                                                     |
//|  16  for rendering at high resolution for an export.             |
//|                                                                  |
//| Part 4's demo puts all four side by side and prints the timings, |
//| so you can pick from evidence rather than from this comment.     |
