I use and recommend Enlightenment Foundation Libraries (EFL, http://enlightenment.org), specially Evas (canvas) and Edje (theme, with animations and transitions). It is very lightweight and can use hardware acceleration when possible, with optimized (sse, mmx, altivec) C replacement. I wrote DirectFB engine some time ago and Denis did a review of it. Denis said to make fully use of hardware acceleration for blits we need to change image allocation to hardware, then paint it with pixels, not hard to do, but I'm not doing it now... patches are welcome or you can consider hiring our company to do such work. Compared to SDL, EFL offers much more primitives and thus can provide many optimizations, like occlusion culling and dirty area/movement. Compared to Qt 4.x, it provides a bit less canvas primitives (no vectors, for instance), but it provides Edje, a very helpful piece of EFL. Also, EFL is BSD with one piece in LGPL, while Qt is GPL or commercial. You can find lots of information about EFL on my blog (http://blog.gustavobarbieri.com.br/) or company news (http://profusion.mobi/taxonomy/term/2).
