Subject: tethering: provide a function to get framebuffer on Mac OS X.
X-Git-Tag: Tizen_Studio_1.3_Release_p2.3.1~263^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=798f94328e10b920629ff2e827d5ce8f9ee8a052;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.
