I'd agree if these changes were any more correct. But you weren't storing pointers in smaller-size integers or doing stupid stuff like that previously, you were just merely limiting the size of an image plane to 2 gigabytes. Since a frame size that large is not in any way realistic, please elaborate how the previous types were more wrong than the new interface. Your reasoning cannot be "because these are pointer offsets", because with that puristical and theoretical argument, the choice of a size_t is equally wrong, as it should be ptrdiff_t then. Fortunately, both size_t and int work perfectly without disadvantages in any real use case. The only practical difference is breaking old plugins or not.
