Subject: [PATCH] Non-constant access to image data.

Sometimes something needs to modify the data (in similar way it modifies
e.g. MeshData) and there is no reason to forbid that, as the data must
be non-const for delete[] operator anyway. There might be slight problem
with ImageWrapper, which should be able to wrap const data, but
currently nothing needs it.
