bugref:8282: Additions/linux: submit DRM driver to the Linux kernel: move all graphics device-related header files to a separate sub-directory and add that to the include path where they are needed. The intention is too be able to remove the VBox/ include folder in the DRM driver package.

1783	* different GPUs with roughly the same features. In most cases GPUs from a
1784	* certain family differ in clockspeeds, the amount of video memory and the
1785	* number of shader pipelines.
1786	*
1787	* A Direct3D device object contains the PCI id (vendor + device) of the
1788	* videocard which is used for rendering. Various applications use this
1789	* information to get a rough estimation of the features of the card and
1790	* some might use it for enabling 3d effects only on certain types of
1791	* videocards. In some cases games might even use it to work around bugs
1792	* which happen on certain videocards/driver combinations. The problem is
1793	* that OpenGL only exposes a rendering string containing the name of the
1794	* videocard and not the PCI id.
1795	*
1796	* Various games depend on the PCI id, so somehow we need to provide one.
1797	* A simple option is to parse the renderer string and translate this to
1798	* the right PCI id. This is a lot of work because there are more than 200
1799	* GPUs just for Nvidia. Various cards share the same renderer string, so
1800	* the amount of code might be 'small' but there are quite a number of
1801	* exceptions which would make this a pain to maintain. Another way would
1802	* be to query the PCI id from the operating system (assuming this is the
1803	* videocard which is used for rendering which is not always the case).
1804	* This would work but it is not very portable. Second it would not work
1805	* well in, let's say, a remote X situation in which the amount of 3d
1806	* features which can be used is limited.
1807	*
1808	* As said most games only use the PCI id to get an indication of the
1809	* capabilities of the card. It doesn't really matter if the given id is
1810	* the correct one if we return the id of a card with similar 3d features.
1811	*
1812	* The code below checks the OpenGL capabilities of a videocard and matches
1813	* that to a certain level of Direct3D functionality. Once a card passes
1814	* the Direct3D9 check, we know that the card (in case of Nvidia) is at
1815	* least a GeforceFX. To give a better estimate we do a basic check on the
1816	* renderer string but if that won't pass we return a default card. This
1817	* way is better than maintaining a full card database as even without a
1818	* full database we can return a card with similar features. Second the
1819	* size of the database can be made quite small because when you know what
1820	* type of 3d functionality a card has, you know to which GPU family the
1821	* GPU must belong. Because of this you only have to check a small part of
1822	* the renderer string to distinguishes between different models from that
1823	* family.
1824	*
1825	* The code also selects a default amount of video memory which we will
1826	* use for an estimation of the amount of free texture memory. In case of
1827	* real D3D the amount of texture memory includes video memory and system
1828	* memory (to be specific AGP memory or in case of PCIE TurboCache /
1829	* HyperMemory). We don't know how much system memory can be addressed by
1830	* the system but we can make a reasonable estimation about the amount of
1831	* video memory. If the value is slightly wrong it doesn't matter as we
1832	* didn't include AGP-like memory which makes the amount of addressable
1833	* memory higher and second OpenGL isn't that critical it moves to system
1834	* memory behind our backs if really needed. Note that the amount of video
1835	* memory can be overruled using a registry setting. */
