# Biblioteca compartilhada dos scripts de build dos jogos feitos com a SGE (Pygame SGE, de onpon4, LGPL-3.0 ou
# posterior; as extensoes xSGE tambem, LGPL-3.0+). Hoje: Hexoshi, ReTux, Pacewar e Tangomon.
#
# O SGE roda o laco principal e os dialogos de forma bloqueante, o que trava o navegador (pygbag). Dois patches nossos,
# publicados junto do fonte de cada jogo, trocam isso por corrotinas:
#   sge-async.patch       sge/dsp.py: Game.start() vira "async def" e cede ao navegador uma vez por quadro
#                         (_wait_frame no lugar de regulate_speed, que nao dorme mais); Game.pause() so marca a pausa e o
#                         laco principal roda um quadro dela por vez (_paused_frame); ganchos modal_active/modal_step.
#   xsge_gui-async.patch  xsge_gui/__init__.py: Dialog.show() nao tem mais laco proprio: entra numa fila (_ModalRunner),
#                         que o laco do SGE avanca um quadro por vez. show() volta logo; "on_close" roda depois que o
#                         dialogo fecha (show_message, get_text_entry e get_menu_selection tambem aceitam on_close).
# O uniseg (so quebra de linha, opcional no SGE) nao e incluido.
#
# Uso: source sge-libs.sh; sge_libs <cache> <destino> sge xsge_gui ...   (baixa, confere o sha256, extrai so os pacotes
# Python e aplica os patches). Os tarballs e os patches vao no bundle.yaml de cada jogo como fonte hospedado.
