Fix Bug 693102: Overflows in large pixmap indexing.
When we allocate a pixmap > 2G, but < 4G, the index into that
pixmap, when calculated as an int can be negative. Fix this with
various casts to unsigned int.
If we ever move to support >4G images we'll need to rejig the
casting to cast each part of the element to ptrdiff_t first.
