[CSS 21] Diagram in 17.5.3 Table height algorithms

Diagram showing the effect of various values of 'vertical-align' on
table cells.
http://www.w3.org/TR/CSS21/images/cell-align.png

This diagram is too small and lacks contrast (light gray on white,
with some dashed 1px light gray borders). On an iMac/MacBook, the
padding is barely visible, if at all. The important legend that reads
"added padding (to make cell as high as the row)" is way too small.

I think it would help understanding this section (vertical-align, cell
height, row height) if this diagram could be redrawn.
