about the tabular vertical alignment - changeset/33780

[Uwe Stöhr]

In http://www.lyx.org/trac/changeset/33780
I implemented LaTeX's logic of the vertical table alignment:

- the highest cell in the row is taken as base for the alignment of the other 
cells
  (i.e. if this cell is e.g. top aligned, its first text line is takes as 
alignment baseline)
- all other cells are aligned along the alignment baseline according to their 
settings



There are however 2 alignment issues left:


- the table row height needs to be increased and the cell lines drawn 
accordingly in the following cases
  - highest cell alignment = top
    - another cell, alignment = middle or bottom
  - highest cell alignment = bottom
    - another cell, alignment = top or middle



thanks and regards
Uwe

Attached is a LyX example file that demonstrate that the valign-related drawing of the cell contents is now correct compared to the PDF output. - the cursor positions are incorrect when a cell has a valignment (this bug was already there before my commits) I must admit that it costs me some hours to read into the metrics stuff and I still haven't fully understood the ascent/descent calculation for tables. Can therefore please someone else have a look at the remaining issues? Edwin, Vincent?
