Hi Donal,

The TS-7390 has built in bliting functions for moving rectangular regions on 
and between the eight available screen buffers. I use these capabilities to 
implement my graphics library, and although I don't do many animations, I've 
been happy with the CPU loading.

I'm not sure how these functions could be added to QT4.5 if they're not already 
being used - I was under the impression that the Linux frame buffer driver had 
been modified to use the functions.

If the blitting functions are not being used by QT4.5, possibly incorporating 
these functions where possible may lead to a speed increase.

Regards,

PJE
