Subject: Enable GL_CULL_FACE in OpenGL samples.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/948f48e7257086aef54f5ce853ff558014799338?hp=616ae1e8434e55bc11dcd0570e96a610bc7e88e5

Enable GL_CULL_FACE in OpenGL samples.

Without it, the hidden faces are shown resulting in wrong display of both the
cube and the penguin, at least with Mesa (but it also seems to be the correct
thing to do according to OpenGL documentation).
