    /* Above is a list of Nvidia and ATI GPUs. Both vendors have dozens of
     * different GPUs with roughly the same features. In most cases GPUs from a
     * certain family differ in clockspeeds, the amount of video memory and the
     * number of shader pipelines.
     *
     * A Direct3D device object contains the PCI id (vendor + device) of the
     * videocard which is used for rendering. Various applications use this
     * information to get a rough estimation of the features of the card and
     * some might use it for enabling 3d effects only on certain types of
     * videocards. In some cases games might even use it to work around bugs
     * which happen on certain videocards/driver combinations. The problem is
     * that OpenGL only exposes a rendering string containing the name of the
     * videocard and not the PCI id.
     *
     * Various games depend on the PCI id, so somehow we need to provide one.
     * A simple option is to parse the renderer string and translate this to
     * the right PCI id. This is a lot of work because there are more 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.
     *
     * The code also selects a default amount of video memory which we will
     * use for an estimation of the amount of free texture memory. In case of
     * real D3D the amount of texture memory includes video memory and system
     * memory (to be specific AGP memory or in case of PCIE TurboCache /
     * HyperMemory). We don't know how much system memory can be addressed by
     * the system but we can make a reasonable estimation about the amount of
     * video memory. If the value is slightly wrong it doesn't matter as we
     * didn't include AGP-like memory which makes the amount of addressable
     * memory higher and second OpenGL isn't that critical it moves to system
     * memory behind our backs if really needed. Note that the amount of video
     * memory can be overruled using a registry setting. */
