Resolution Note:
You can't expect to lookup glEnable function manually from a system OpenGL library, store the current OpenGL renderer status into a boolean, and then call glEnable without the check in question. Some OpenGL driver implementations might give a free pass on this if there is no OpenGL context set available at all, but don't count on it.
void OnPreRender()
{
if (mIsOpenGL)
glEnable(GL_VERTEX_PROGRAM_POINT_SIZE);
glEnable(GL_POINT_SMOOTH);
}
