So I'm right in supposing that in the KisTileMgr functions

        KisPixelDataSP pixelData(Q_INT32 x1, Q_INT32 y1, Q_INT32 x2, Q_INT32 
y2, Q_INT32 mode);
        void releasePixelData(KisPixelDataSP pd);
        void readPixelData(Q_INT32 x1, Q_INT32 y1, Q_INT32 x2, Q_INT32 y2, 
QUANTUM *buffer, Q_UINT32 stride);
        void readPixelData(KisPixelDataSP pd);
        void writePixelData(Q_INT32 x1, Q_INT32 y1, Q_INT32 x2, Q_INT32 y2, 
QUANTUM
*buffer, Q_UINT32 stride);
        void writePixelData(KisPixelDataSP pd);

The coordinates are those for the whole image? That would make life a lot
easier. Having tile-aware methods in KisPainter can come later, when the
speed is needed.
