# gzdoom_pbuf_run.sh - in-guest GZDoom run recipe for the offscreen SDL2
# GLX-pbuffer harness. Run this inside the guest after push_gl_tools.sh has
# placed the shims in /tmp. It prints the exact command line, runs GZDoom
# under timeout, and leaves the output in $GZLOG.
#
# Environment (all overridable):
# GZDOOM_BIN default /opt/gzdoom/gzdoom
# WAD default /usr/share/games/doom/freedoom2.wad
# GZCAP default /tmp/gzframes.bin (sdl_cap.so capture file)
# GZPBUF_W/H default 640/480 (gz_pbuf.so pbuffer size)
# GZLOG default /tmp/gzdoom-pbuf.log
# TIMEOUT default 300 seconds
# GZ_ARGS extra GZDoom args appended after the base set
# GZ_DETACH default 0; set 1 to setsid/nohup the run and return
# DISPLAY default :0
#
# The base args are windowed GL: +set vid_fullscreen 0, 640x480, OpenGL
# backend 0, +vid_rendermode 4 (GL mode), MAP01. The preload order matters:
# sdl_cap.so first (captures SDL_GL_SwapWindow), gz_pbuf.so second (turns the
# SDL GL context into a GLX pbuffer and the swap into glFinish).
