> ASSERTION FAILED: m_transparencyCount > 0

Hmpf, the problem is the m_transparencyCount generalization. Qt maintains a different count "layerCount" returned by isInTransparentLayer(), and it calls endTransparencyLayer too often, compared to all other ports - to support image clipping.

Cairo has similar needs (mask image operation during restore()) but doesn't suffer from the problem - can this be reused instead? I hope Zoltan can have a look.
