With an explicit Present Mode (Mailbox, Immediate), the VSync option did
nothing: the setting replaced vanilla's choice even with VSync on, so a
window kept running uncapped. Vanilla's VSync means Fifo, in a window and in
fullscreen alike. Now VSync on always presents with Fifo, and the Present
Mode setting chooses only while VSync is off (Auto keeps vanilla's choice:
Immediate, else Mailbox, else Fifo). The choice is one tested function,
window::chosen_present_mode.

A Horizon graphics setting (Performance, off by default, batteryMode in
horizon-graphics.txt): at most 60 frames per second in a world, 30 in menus
without a world or behind other windows, and half the automatic worker
threads. It only changes when frames are drawn; ticks and what frames show
are untouched.

At render distance 32 the single section arena grew past the 4 GiB buffer
limit and the renderer panicked. Sections now live in pages of at most
256 MiB (or the device's buffer limit); draws keep their order and bind each
page once per run of consecutive draws in it, so translucent sections stay
back to front. docs/graphics.md describes the settings, the benchmark and
what changed; graphics_bench.py --compare prints a before/after table and
keeps each game's log.
