Description jjc 2005-10-02 10:33:25 UTC 
When using most popular Thai fonts (eg the Windows Angsana and Cordia fonts but
not the Tahoma font), OOo uses far too thick a line for underlining: this looks
very ugly.  This happens on both Windows and Linux.

It seems that vcl computes the underline thickness using a heuristic based on
the descender height, instead of getting it from the font (using the
underlineThickness field of the post table in a Truetype font).  This heuristic
appears to work poorly for typical Thai fonts.

ssa->hdu: we have these problems with some korean fonts as well. may be you can
come up with a better heuristic or a better suited font parameter that can be used.

In CWS vcl56 I added a heuristic to handle fonts with relatively big descents
better.
