+   !   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
