Subject: eglGetDisplay now returns the same display handle for every call.
X-Git-Tag: TizenStudio_2.0_p2.3~1273^2~77
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8cc2e6f6c37665b2e7ae21c090004b5810731c8d;p=sdk%2Femulator%2Fqemu.git

eglGetDisplay now returns the same display handle for every call.
Fixed races in gles.
Replaced unpack alignment with pack/unpack alignment.
