I've now implemented driver support for arcs (including rotated arcs) in the Qt driver too. I'm no Qt expert, but all looks to work fine. There does seem to be a lot of duplicated code in the Qt driver for the different flavours of device. From a maintenance point of view it would be good to streamline this a bit. Since it is all in C++ this should be perfectly do-able. Another little project for the list...
