opj_tcd_tile_t contains a numpix variable, which counts the number of pixels in a tile.
It is currently of type OPJ_INT32, but should be changed to OPJ_INT64 to avoid overflow.

I think just changing it to OPJ_UINT32 should be fine.

Actually, I don't think the library will be able to decode tiles larger than 2^31 pixels in the foreseeable
future, so I am closing this issue.
