Well they know in a way, but they shouldn't have to care about that! The
problem with insets is that we mix there realtive and absolut positions.
This may be good for the draw(x,baseline), but for example we have to maintain
a absolute x position for the cursor, while the y position is relative!

I think that to be able to have this type of insets we would just have to
return also the value for the new baseline, but I think this is a really
bad move, as think of different fonts and how would you know inside the
inset that the second row of your inset should be higher because there is
a following text with higher font so that in this row ascent/descent change.
The real good move would be that the inset returns the rows it will span,
then LyXText can call a draw for the whole inset or a draw for single rows
(this obviouly only on inset-types with DO span multiple rows). This would
be a really needed change as then LyXText could do a really good work
drawing the insets row by row, and don't draw unneeded stuff. Think of a
tabular inset which spanns 3 whole pages. Think of 1 row as 1 tabular row,
now LyXText can construct it's row-structure also viewing a tabular as
single rows and so do a much better job when having to repaint part of it.
What do you think about this?
Well to you Angus :), for now you have to live with it that you don't have
that form of half-row, you can only paint 1, 2 or more WHOLE rows. The inset
is always rectangular!
