 I doubt somebody on this list knows enough to tell for sure how likely it's 
to encounter X11 without XRender. Before LO I used to be a window manager 
maintainer and I'm not sure. XRender works even remotely, so I expect it's 
not available only if the X server doesn't support it, which means either too 
old, custom X11 implementation maybe, or broken drivers? That's a question 
for X11 developers.

 But if XRender support is the problem, then it might be sufficient to ask if 
we can afford to hard-require it. I'd say if René wouldn't have a problem 
with it then I doubt anybody else would.
