Print warning messages for multipass blur 

Multipass blur is not properly implemented for xrender backend. There is
visible artifacts when it is used. And it is quite difficult to
implement correctly and efficiently for the xrender backend.

Print a warning message for multipass blur so we can survey whether it
is actually been used.

No functionality is removed in this commit.
