1884      * certain family differ in clockspeeds, the amount of video memory and the
1885      * number of shader pipelines.
1886      *
1887      * A Direct3D device object contains the PCI id (vendor + device) of the
1888      * videocard which is used for rendering. Various applications use this
1889      * information to get a rough estimation of the features of the card and
1890      * some might use it for enabling 3d effects only on certain types of
1891      * videocards. In some cases games might even use it to work around bugs
1892      * which happen on certain videocards/driver combinations. The problem is
1893      * that OpenGL only exposes a rendering string containing the name of the
1894      * videocard and not the PCI id.
1895      *
1896      * Various games depend on the PCI id, so somehow we need to provide one.
1897      * A simple option is to parse the renderer string and translate this to
1898      * the right PCI id. This is a lot of work because there are more than 200
1899      * GPUs just for Nvidia. Various cards share the same renderer string, so
1900      * the amount of code might be 'small' but there are quite a number of
1901      * exceptions which would make this a pain to maintain. Another way would
1902      * be to query the PCI id from the operating system (assuming this is the
1903      * videocard which is used for rendering which is not always the case).
1904      * This would work but it is not very portable. Second it would not work
1905      * well in, let's say, a remote X situation in which the amount of 3d
1906      * features which can be used is limited.
1907      *
1908      * As said most games only use the PCI id to get an indication of the
1909      * capabilities of the card. It doesn't really matter if the given id is
1910      * the correct one if we return the id of a card with similar 3d features.
1911      *
1912      * The code below checks the OpenGL capabilities of a videocard and matches
1913      * that to a certain level of Direct3D functionality. Once a card passes
1914      * the Direct3D9 check, we know that the card (in case of Nvidia) is at
1915      * least a GeforceFX. To give a better estimate we do a basic check on the
1916      * renderer string but if that won't pass we return a default card. This
1917      * way is better than maintaining a full card database as even without a
1918      * full database we can return a card with similar features. Second the
1919      * size of the database can be made quite small because when you know what
1920      * type of 3d functionality a card has, you know to which GPU family the
1921      * GPU must belong. Because of this you only have to check a small part of
1922      * the renderer string to distinguishes between different models from that
1923      * family.
1924      *
1925      * The code also selects a default amount of video memory which we will
1926      * use for an estimation of the amount of free texture memory. In case of
1927      * real D3D the amount of texture memory includes video memory and system
1928      * memory (to be specific AGP memory or in case of PCIE TurboCache /
1929      * HyperMemory). We don't know how much system memory can be addressed by
1930      * the system but we can make a reasonable estimation about the amount of
1931      * video memory. If the value is slightly wrong it doesn't matter as we
1932      * didn't include AGP-like memory which makes the amount of addressable
1933      * memory higher and second OpenGL isn't that critical it moves to system
1934      * memory behind our backs if really needed. Note that the amount of video
1935      * memory can be overruled using a registry setting. */
