Subject: tethering: provide a function to get framebuffer on Mac OS X.
X-Git-Tag: TizenStudio_2.0_p3.0~398^2~45
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=50a280fc18461b2b6d35e26108e67255a3ba44c8;p=sdk%2Femulator%2Fqemu.git

tethering: provide a function to get framebuffer on Mac OS X.

maru_shm module is used to draw display instead of maru_sdl on Mac OS X.
so, add a function for extracting framebuffer from display.
