Subject: [PATCH] arena: wheel zoom between 1P and discrete 3P distances
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Scroll up = zoom in (toward 1P). Scroll down = zoom out (pulls camera
back through 3P distances 3, 5, 8, 12). Middle-click still toggles
between 1P and a default 3P level. POV HUD label now shows the active
zoom distance, e.g. "3P ×5".
