1963      * certain family differ in clockspeeds, the amount of video memory and the
1964      * number of shader pipelines.
1965      *
1966      * A Direct3D device object contains the PCI id (vendor + device) of the
1967      * videocard which is used for rendering. Various applications use this
1968      * information to get a rough estimation of the features of the card and
1969      * some might use it for enabling 3d effects only on certain types of
1970      * videocards. In some cases games might even use it to work around bugs
1971      * which happen on certain videocards/driver combinations. The problem is
1972      * that OpenGL only exposes a rendering string containing the name of the
1973      * videocard and not the PCI id.
1974      *
1975      * Various games depend on the PCI id, so somehow we need to provide one.
1976      * A simple option is to parse the renderer string and translate this to
1977      * the right PCI id. This is a lot of work because there are more than 200
1978      * GPUs just for Nvidia. Various cards share the same renderer string, so
1979      * the amount of code might be 'small' but there are quite a number of
1980      * exceptions which would make this a pain to maintain. Another way would
1981      * be to query the PCI id from the operating system (assuming this is the
1982      * videocard which is used for rendering which is not always the case).
1983      * This would work but it is not very portable. Second it would not work
1984      * well in, let's say, a remote X situation in which the amount of 3d
1985      * features which can be used is limited.
1986      *
1987      * As said most games only use the PCI id to get an indication of the
1988      * capabilities of the card. It doesn't really matter if the given id is
1989      * the correct one if we return the id of a card with similar 3d features.
1990      *
1991      * The code below checks the OpenGL capabilities of a videocard and matches
1992      * that to a certain level of Direct3D functionality. Once a card passes
1993      * the Direct3D9 check, we know that the card (in case of Nvidia) is at
1994      * least a GeforceFX. To give a better estimate we do a basic check on the
1995      * renderer string but if that won't pass we return a default card. This
1996      * way is better than maintaining a full card database as even without a
1997      * full database we can return a card with similar features. Second the
1998      * size of the database can be made quite small because when you know what
1999      * type of 3d functionality a card has, you know to which GPU family the
2000      * GPU must belong. Because of this you only have to check a small part of
2001      * the renderer string to distinguishes between different models from that
2002      * family.
2003      *
2004      * The code also selects a default amount of video memory which we will
2005      * use for an estimation of the amount of free texture memory. In case of
2006      * real D3D the amount of texture memory includes video memory and system
2007      * memory (to be specific AGP memory or in case of PCIE TurboCache /
2008      * HyperMemory). We don't know how much system memory can be addressed by
2009      * the system but we can make a reasonable estimation about the amount of
2010      * video memory. If the value is slightly wrong it doesn't matter as we
2011      * didn't include AGP-like memory which makes the amount of addressable
2012      * memory higher and second OpenGL isn't that critical it moves to system
2013      * memory behind our backs if really needed. Note that the amount of video
