[Qemu-devel] [PATCH] sdl: Do not disable screensaver by default

[Jan Kiszka <jan.kiszka@web.de>]

From: Jan Kiszka <jan.kiszka@siemens.com>

Unless we are running in full-screen mode, QEMU's SDL window should not
disable the host's screensaver. The user can still change this behaviour
by setting the environment variable SDL_VIDEO_ALLOW_SCREENSAVER as
desired.

Cool, thanks for digging out SDL_VIDEO_ALLOW_SCREENSAVER. I came across
by this issue as well but I was too lazy to analyze to reason. This
patch solves it for me.
