     * than 200 GPUs just for Nvidia. Various cards share the same renderer string, so the amount of code might
     * be 'small' but there are quite a number of exceptions which would make this a pain to maintain.
     * Another way would be to query the PCI id from the operating system (assuming this is the videocard which
     * is used for rendering which is not always the case). This would work but it is not very portable. Second
     * it would not work well in, let's say, a remote X situation in which the amount of 3d features which can be used
     * is limited.
     *
     * As said most games only use the PCI id to get an indication of the capabilities of the card.
     * It doesn't really matter if the given id is the correct one if we return the id of a card with
     * similar 3d features.
     *
     * The code below checks the OpenGL capabilities of a videocard and matches that to a certain level of
     * Direct3D functionality. Once a card passes the Direct3D9 check, we know that the card (in case of Nvidia)
     * is at least a GeforceFX. To give a better estimate we do a basic check on the renderer string but if that
     * won't pass we return a default card. This way is better than maintaining a full card database as even
     * without a full database we can return a card with similar features. Second the size of the database
     * can be made quite small because when you know what type of 3d functionality a card has, you know to which
     * GPU family the GPU must belong. Because of this you only have to check a small part of the renderer string
     * to distinguishes between different models from that family.
