NEW: games/renpy 8.5.3

Hi,

Attached is a new port of Ren'Py 8.5.3, the visual novel engine.
https://www.renpy.org/

games/renpy was removed on 2025-10-18 ("remove py2-only 
ports/games/renpy (has been marked BROKEN for over a year with no 
interest) and pygame_sdl2 (only used by renpy); upstream has a newer 
version supporting Python 3 and newer Cython if someone wants to readd 
it").

This is that re-add: upstream is Python 3 with current Cython, and 
pygame_sdl2 has been absorbed into the Ren'Py tree, so it is a single 
port now, with no pygame_sdl2 to bring back.

Notes:

- One build workaround: upstream's setup.py derives CFLAGS/LDFLAGS from 
pkg-config but never CXXFLAGS, so the single C++ module misses the SDL2 
include path; the port adds the pkg-config cflags via CPPFLAGS in 
do-build. Already fixed properly upstream, so this disappears at the 
next release update.
- One patch: a backport of upstream's fix for Python 3.14 (where 
functools.partial became a method descriptor), without which any 
save/persistent file containing a datetime fails to unpickle.
- The launcher, template projects and bundled games are installed under 
share/renpy, following the old port's layout.

Tested on amd64/-current (Intel HD 6000): builds from scratch, packages, 
installs and deinstalls cleanly; `renpy the_question lint` passes 
headless from the installed package; the launcher runs under X from the 
installed package with working audio and save/load. Full commercial 
Ren'Py games run start to finish on the same machine and engine version.

Known limitation: Ren'Py's optional Live2D animation support cannot work 
on OpenBSD (it needs Live2D Cubism Core, a proprietary binary-only 
library with no BSD build). This affects a subset of commercial games. 
Noted in pkg/README.

I am not able to commit to being MAINTAINER right now, so I have left it 
unset. I'll be happy if someone wants to take it. I will fix anything 
that comes up during review.

Thank you,
