 837      * in case of the latest videocards in the number of pixel/vertex pipelines.
 838      *
 839      * A Direct3D device object contains the PCI id (vendor + device) of the videocard which is used for
 840      * rendering. Various games use this information to get a rough estimation of the features of the card
 841      * and some might use it for enabling 3d effects only on certain types of videocards. In some cases
 842      * games might even use it to work around bugs which happen on certain videocards/driver combinations.
 843      * The problem is that OpenGL only exposes a rendering string containing the name of the videocard and
 844      * not the PCI id.
 845      *
 846      * Various games depend on the PCI id, so somehow we need to provide one. A simple option is to parse
 847      * the renderer string and translate this to the right PCI id. This is a lot of work because there are more
 848      * than 200 GPUs just for Nvidia. Various cards share the same renderer string, so the amount of code might
 849      * be 'small' but there are quite a number of exceptions which would make this a pain to maintain.
 850      * Another way would be to query the PCI id from the operating system (assuming this is the videocard which
 851      * is used for rendering which is not always the case). This would work but it is not very portable. Second
 852      * it would not work well in, let's say, a remote X situation in which the amount of 3d features which can be used
 853      * is limited.
 854      *
 855      * As said most games only use the PCI id to get an indication of the capabilities of the card.
 856      * It doesn't really matter if the given id is the correct one if we return the id of a card with
 857      * similar 3d features.
 858      *
 859      * The code below checks the OpenGL capabilities of a videocard and matches that to a certain level of
 860      * Direct3D functionality. Once a card passes the Direct3D9 check, we know that the card (in case of Nvidia)
 861      * is at least a GeforceFX. To give a better estimate we do a basic check on the renderer string but if that
 862      * won't pass we return a default card. This way is better than maintaining a full card database as even
 863      * without a full database we can return a card with similar features. Second the size of the database
 864      * can be made quite small because when you know what type of 3d functionality a card has, you know to which
 865      * GPU family the GPU must belong. Because of this you only have to check a small part of the renderer string
