The resources (display information, pointers, bit maps, and fonts) are stored in DLL files. Some of these resources are linked by the presentation driver when it is first enabled, others are loaded by the application with WinLoadPointer.
The two system fonts are queried by the graphics engine when the presentation driver is loaded. When the presentation driver has a default font, it returns the handle of the font, as requested. When this function returns a NULL handle for the system font, the graphics engine default fonts are used instead (see Font Functions).
