35 * The Windows Game dll provides a number of functions designed to allow
36 * programmers to bypass Gdi and write directly to video memory. The intention
37 * was to bolster the use of Windows as a gaming platform and remove the
38 * need for Dos based games using 32 bit Dos extenders.
40 * This initial approach could not compete with the performance of Dos games
41 * (such as Doom and Warcraft) at the time, and so this dll was eventually
42 * superseded by DirectX. It should not be used by new applications, and is
43 * provided only for compatibility with older Windows programs.

52 * WinG DIB bitmaps can be selected into DC and then scribbled upon
53 * by GDI functions. They can also be changed directly. This gives us
55 * - use original WinG 16-bit DLL
56 * requires working 16-bit driver interface
57 * - implement DIB graphics driver from scratch
59 * - use shared pixmaps
60 * won't work with some videocards and/or videomodes
