| The three green rectangles below show ascent, character, and descent sizes |
| from the left. The ascent and descent are overridden by 100% and 50% of the |
| specified font size, respectively. The test applies font-size-adjust and font |
| metric overrides simultaneously to text. As we double the text size with |
| font-size-adjust, the ascent and descent override should scale accordingly |
| to double their size. |
