How about something like this: When a line has been found to contain
<sup> or <sub> tag pairs, increase the height of the line, and pad the NON
sup/sub with whitespace above or below, as necessary. Here's an example
(excuse the horrid ascii art):
- ------------------------------------------------------------
space above .-----.
| |
.--. .--. | .---' <- this is a sup character
| | | | | |
| `--' | | `---.
| | | |
| .--. | `-----'
| | | | <- space below sup letters
`--' `--' <- this is normal, sit on bottom of row
- -------------------------------------------------------------
This of course, would only appear in rows which contain the <sup> or
<sub> elements, not on all rows. If you've ever seen how MathML is
reperesented in a webpage, this should be a bit easier to understand.
The opposite would be for sub, where the "normal" font appears at
the top of the line row with a few pixels of spacing underneath the "normal"
letters, and the "sub" characters would sit on the bottom of the row itself,
with a few pixels of space above the font characters in that row.
Just one idea... and fairly harmless to do, easy to support.
