Subject: YaGL: Add OpenGL 3.1 without ES3 to supported versions
X-Git-Tag: Tizen_Studio_1.3_Release_p2.3.1~475^2~47
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1adb8151daff10408202c98ea593258803623595;p=sdk%2Femulator%2Fqemu.git

YaGL: Add OpenGL 3.1 without ES3 to supported versions

Even if OpenGL 3.1 doesn't support GL_ARB_ES3_compatibility
we still should use it instead of 2.1 because in case of mesa
3.1 has much smaller memory footprint
