arrange: use int not size_t for title offsets

This changes `apply_tabbed_layout` and `apply_stacked_layout` to use
`int` instead of `size_t`. This is necessary for tabbed and stacked
containers to be positioned correctly when the y-location is negative.
The reasoning for this is signed plus unsigned is always an unsigned
value. This was causing the y-location of the container to be
positioned near `INT_MIN` due to an unsigned integer underflow
