The rectangle used to correct the compose settings when changing the
format was created inside a helper function and not where it was used.
This is confusing and makes the code harder to read, fix this.

This cleanup is made possible due to refactoring elsewhere and there is
no functional change.

I would rename fmt_rect to something more descriptive. Maybe full_rect,
compose_bounds, ... ? Apart from that,
