Would it be possible to implement Qt4 text engine in terms of KPainter, e.g.
by extending KPainter API with the necessary methods, things like
drawGlyph(uint glyph, QWMatrix&)?

What would be needed for that?

Somehow Tomasz thought it was necessary to introduce KFontMetrics, i.e. an
own implementation for KPainter.
I don't know enough about text rendering to be able to tell if this is relly
necessary.
Tomasz claims it is necessary to e.g. fetch kerning information.

Does there already exists information about Qt4 QFontMetrics?
