Thank you for your help. I'm trying to convert my code again at 
the moment, but ran into a new problem: I need to pass a pointer 
to the data into a C function. It seems that the .ptr property is 
not available, and using & caused dmd to segfault (currently 
running a Dustmite reduction for that). Is there any clean way to 
get a pointer to the underlying data?
