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41 * superseded by DirectX.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

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