[Molecular-evolution] re-drawing trees with overlapping labels

One of our users has a problem : his phylogenetic trees contain many
taxons and the names tend to overlap. For trees made with the PHYLIP
programs seqboot-dnapars-consense a method that works is to use
drawtree, which has various algorithms to re-draw the branches and the
labels in various orientations. But for trees made with PhyML or
MrBayes, and that have included bootstrap values, there is a problem.
The popular tree editor TreeView does not allow to re-orient the labels.
Does someone know a way to do it (either using a performant tree editor
or by procesing the pictorial representation of the tree in an image
editor, preferable freeware) ?
