	 * For others, always use OpenGL.  Allow forcing to D3D as an advanced option.
	 *
	 * If we're missing acceleration when we load D3D8 due to a card being in the
	 * D3D list, it means we need drivers and that they do exist.
	 *
	 * If we try to load OpenGL and we're missing acceleration, it may mean:
	 *  1. We're missing drivers, and they just need upgrading.
	 *  2. The card doesn't have drivers, and it should be using D3D8.  In other words,
	 *     it needs an entry in this table.
	 *  3. The card doesn't have drivers for either.  (Sorry, no S3 868s.)  Can't play.
	 * 
	 * In this case, fail to load; don't silently fall back on D3D.  We don't want
	 * people unknowingly using D3D8 with old drivers (and reporting obscure bugs
	 * due to driver problems).  We'll probably get bug reports for all three types.
	 * #2 is the only case that's actually a bug.
	 *
	 * Actually, right now we're falling back.  I'm not sure which behavior is better.
