Get the OpenGL graphics portable.

There's still reports of the program crashing and not displaying the voxel world properly. I can't reproduce the bug, but the biggest offender we've had so far for OpenGL issues is here.

int lpAttribList[] = {WX_GL_RGBA, WX_GL_DOUBLEBUFFER, WX_GL_DEPTH_SIZE, 1, 0};

We've had success before in fixing some common OpenGL mistakes by changing this attribute list sent to the OpenGL canvas. If I could reproduce the issue, I'll try playing with what other people have tried, and maybe just playing with all the valid attributes.

Pinging @sammywhammy on this. He apparently had these issues with a VM on Linux Mint, but solved them by disabling 3D acceleration in VirtualBox, and symbolically linking some library?

Not sure about the details yet.

So I did this:
cd /usr/lib/xorg/modules/drivers/
sudo ln -s vboxvideo_drv.so /usr/lib/vboxvideo_drv.so

But I'm not sure it made a difference. As @tefu said, I did disable 3D acceleration in VirtualBox. Also my distro is linux mint 17.1 KDE with an OSX host.
