The problem is, that those functions are then not only used in the
window manager, but also by other programs written with the toolkit.
But in the end, you probably are right. Most of the time it might be
completely unnecessary to have a special text structure.
The real ugliness lies in having two sets of functions. That, or I'm
missing something obvious. Like for example paying the costs of
converting the gapped array into a char* are bearable from time to time.
