2035      * certain family differ in clockspeeds, the amount of video memory and the
2036      * number of shader pipelines.
2037      *
2038      * A Direct3D device object contains the PCI id (vendor + device) of the
2039      * videocard which is used for rendering. Various applications use this
2040      * information to get a rough estimation of the features of the card and
2041      * some might use it for enabling 3d effects only on certain types of
2042      * videocards. In some cases games might even use it to work around bugs
2043      * which happen on certain videocards/driver combinations. The problem is
2044      * that OpenGL only exposes a rendering string containing the name of the
2045      * videocard and not the PCI id.
2046      *
2047      * Various games depend on the PCI id, so somehow we need to provide one.
2048      * A simple option is to parse the renderer string and translate this to
2049      * the right PCI id. This is a lot of work because there are more than 200
2050      * GPUs just for Nvidia. Various cards share the same renderer string, so
2051      * the amount of code might be 'small' but there are quite a number of
2052      * exceptions which would make this a pain to maintain. Another way would
2053      * be to query the PCI id from the operating system (assuming this is the
2054      * videocard which is used for rendering which is not always the case).
2055      * This would work but it is not very portable. Second it would not work
2056      * well in, let's say, a remote X situation in which the amount of 3d
2057      * features which can be used is limited.
2058      *
2059      * As said most games only use the PCI id to get an indication of the
2060      * capabilities of the card. It doesn't really matter if the given id is
2061      * the correct one if we return the id of a card with similar 3d features.
2062      *
2063      * The code below checks the OpenGL capabilities of a videocard and matches
2064      * that to a certain level of Direct3D functionality. Once a card passes
2065      * the Direct3D9 check, we know that the card (in case of Nvidia) is at
2066      * least a GeforceFX. To give a better estimate we do a basic check on the
2067      * renderer string but if that won't pass we return a default card. This
2068      * way is better than maintaining a full card database as even without a
2069      * full database we can return a card with similar features. Second the
2070      * size of the database can be made quite small because when you know what
2071      * type of 3d functionality a card has, you know to which GPU family the
2072      * GPU must belong. Because of this you only have to check a small part of
2073      * the renderer string to distinguishes between different models from that
2074      * family.
2075      *
2076      * The code also selects a default amount of video memory which we will
2077      * use for an estimation of the amount of free texture memory. In case of
2078      * real D3D the amount of texture memory includes video memory and system
2079      * memory (to be specific AGP memory or in case of PCIE TurboCache /
2080      * HyperMemory). We don't know how much system memory can be addressed by
2081      * the system but we can make a reasonable estimation about the amount of
2082      * video memory. If the value is slightly wrong it doesn't matter as we
2083      * didn't include AGP-like memory which makes the amount of addressable
2084      * memory higher and second OpenGL isn't that critical it moves to system
2085      * memory behind our backs if really needed. Note that the amount of video
