Full Changelog: v2.2.5...v2.2.7

v2.2.7

New: material difference beside the board

Like Lichess, the window now shows which pieces each side is up on,
in a column to the right of the board. Each side's material appears
by its own end of the board, on a small strip in the board's
light-blue square color so both white and black pieces stand out in
either theme. The icons are half the size of a board square and grow
with the board. The side ahead also shows its lead in points (pawn 1,
knight/bishop 3, rook 5, queen 9), e.g. +3. It is worked out from the
pieces on the board, so promotions count.

New: light/dark theme switch

A ☀/🌙 button in the status bar, or the T key, switches the window
between light and dark while it is running. The window still starts
in your system's setting.

Fixed: resuming a game after a reconnect

v2.2.5 sent resume after reconnecting, which not every server
supports. The bot now sends match <opponent> to the player it was
playing, which resumes the adjourned game where it left off, clocks
included.

Improved: lower CPU use with the window open

• The window now redraws once a second during a game, as the clock
  ticks, instead of ten times a second. Moves, clicks and typing
  still update it immediately.
• The console keeps the last 100 lines instead of 2,000.

This matters most where the window is drawn in software, such as
WSL2, where it could take CPU time away from the engine.
