Starting with 5240116f3c we only support
GHC versions 8.4.4 and up (more precisely, the GHC version associated
with stackage lts-12 and up). The imports in question are now in
Prelude and need not be imported explicitly.

Includes a new mode for resizing windows in a more intuitive way, also contains a bug fix that was preventing users from
resiving a window up.
