annotate src/video/nanox/SDL_nxmouse.c @ 4333:55717a755897 SDL-1.2

Switched from setting the period size and count to setting the buffer size directly, based on feedback from the ALSA development list: http://mailman.alsa-project.org/pipermail/alsa-devel/2009-October/022267.html This has the nice side effect of reducing latency on my SBLive! card.
