Simple array init question

[Graham]

I'm not sure why you're concentrating on O(1) random access.  I need a 
static buffer of fixed width & height.  As I mentioned in a previous 
post, I could use a 1D array, but wanted to try a multi dimensional 
array and was puzzled why the initialiser didn't work.  I'm passing this 
array to OpenGL, so I need a contiguous buffer.

Does that explain what I'm after?

Thanks.
