| <!-- |
| ! The 0.3em comes from the following: |
| ! |
| ! * The font is 1em high |
| ! * The line height is 0 |
| ! * The half leading is therefore -0.5em centered around the middle of the font |
| ! * The baseline is 0.2em from the bottom of the font |
| ! * Thus the distance from the baseline to the center is 0.3em |
| ! * The image is placed on the baseline |
| | * The line box has to include the image and the middle of the font |
| ! * Thus the line box is 0.3em high |
