+	 * Some cards simply are too troublesome with OpenGL to ever use it, eg. Voodoos.
+	 * If D3D8 isn't installed on those, complain and refuse to run (by default).
+	 * 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.
+	 *
+	 * If a system is listed as needing D3D, it's important--don't silently fall
+	 * back on OpenGL if it's missing.  (If that would work, we wouldn't use D3D
+	 * on that system to begin with.)
