There is not currently such an API, but of course you could easily build 
one on top of the existing API if you like by allocating a temporary 
pixmap to build the composite image in.  This is precisely what Xft would 
do internally as the X render extension doesn't provide this operation.

By allocating only a temporary pixmap, you wouldn't introduce any permanant
additional memory overhead.

If you added this code to Xft, you might want to optimize the non-Render 
case to avoid the GetImage.
