1038      * in case of the latest videocards in the number of pixel/vertex pipelines.
1039      *
1040      * A Direct3D device object contains the PCI id (vendor + device) of the videocard which is used for
1041      * rendering. Various games use this information to get a rough estimation of the features of the card
1042      * and some might use it for enabling 3d effects only on certain types of videocards. In some cases
1043      * games might even use it to work around bugs which happen on certain videocards/driver combinations.
1044      * The problem is that OpenGL only exposes a rendering string containing the name of the videocard and
1045      * not the PCI id.
1046      *
1047      * Various games depend on the PCI id, so somehow we need to provide one. A simple option is to parse
1048      * the renderer string and translate this to the right PCI id. This is a lot of work because there are more
1049      * than 200 GPUs just for Nvidia. Various cards share the same renderer string, so the amount of code might
1050      * be 'small' but there are quite a number of exceptions which would make this a pain to maintain.
1051      * Another way would be to query the PCI id from the operating system (assuming this is the videocard which
1052      * is used for rendering which is not always the case). This would work but it is not very portable. Second
1053      * it would not work well in, let's say, a remote X situation in which the amount of 3d features which can be used
1054      * is limited.
1055      *
1056      * As said most games only use the PCI id to get an indication of the capabilities of the card.
1057      * It doesn't really matter if the given id is the correct one if we return the id of a card with
1058      * similar 3d features.
1059      *
1060      * The code below checks the OpenGL capabilities of a videocard and matches that to a certain level of
1061      * Direct3D functionality. Once a card passes the Direct3D9 check, we know that the card (in case of Nvidia)
1062      * is at least a GeforceFX. To give a better estimate we do a basic check on the renderer string but if that
1063      * won't pass we return a default card. This way is better than maintaining a full card database as even
1064      * without a full database we can return a card with similar features. Second the size of the database
1065      * can be made quite small because when you know what type of 3d functionality a card has, you know to which
1066      * GPU family the GPU must belong. Because of this you only have to check a small part of the renderer string
1067      * to distinguishes between different models from that family.
1068      *
1069      * The code also selects a default amount of video memory which we will use for an estimation of the amount
1070      * of free texture memory. In case of real D3D the amount of texture memory includes video memory and system
1071      * memory (to be specific AGP memory or in case of PCIE TurboCache/HyperMemory). We don't know how much
1072      * system memory can be addressed by the system but we can make a reasonable estimation about the amount of
1073      * video memory. If the value is slightly wrong it doesn't matter as we didn't include AGP-like memory which
1074      * makes the amount of addressable memory higher and second OpenGL isn't that critical it moves to system
1075      * memory behind our backs if really needed.
