Keith Packard df534d0520 Make GetPictureScreenIfSet check if Render is running ...

This macro originally checked to see if the Render screen private
index had been allocated. When the privates were changed the first
time, there wasn't any need to check as dixLookupPrivate would simply
return NULL in that case. Now that we care, check to see if the key
has been initialized before asking for the value.
