Question about TextPainter and associated drawT() method

[Abdelrazak Younes]

Question for Andre I guess:

This TextPainter class is used nowhere in the code except in a dead code 
(note the if (0 ):

int InsetMathHull::plaintext(Buffer const &, lyx::odocstream & os,
                        OutputParams const &) const
{
        if (0 && display()) {
                Dimension dim;
                TextMetricsInfo mi;
                metricsT(mi, dim);
                TextPainter tpain(dim.width(), dim.height());


Is there any plan for these drawT methods or can I just delete them. It 
will facilitate the elimination of the coordCache global pointer.

Abdel.
