The fillrect was the simplest to implement.  I agree that the others
will be much higher value.

In DirectFB there are a set of benchmarks that run through all of the
different drawing types including filled rectangles.  That is what I am
using as my baseline.

      

I don't know DirectFB. I am not sure if the DirectFB uses the frame buffer
acceleration or its own. 
    

DirectFB has it's own low level gfx drivers. It can use fbdev for mode
switching but that's all.

In fact there is no way to call fbdev accel code from userspace.

  

I'm adding hardware acceleration to the sparc leo driver and this is 
what I am using for user space testing:
