6719e56b5b Ref<> objects must be nested by reference because they potentially store a temporary object 2013-08-11 17:52:43 +02:00

8f4d93a4b7 Fix compilation. 
The Matrix is required to be mutable but it also needs to be a reference and
temporaries do not bind to non-const references - thus we need a hack and
cast away the constness.
