*
* Why haven't we implemented DrvSaveScreenBits? To save code.
*
* When the driver doesn't hook DrvSaveScreenBits, USER simulates on-
* the-fly by creating a temporary device-format-bitmap, and explicitly
* calling DrvCopyBits to save/restore the bits. Since we already hook
* DrvCreateDeviceBitmap, we'll end up using off-screen memory to store
* the bits anyway (which would have been the main reason for implementing

// (i.e., we didn't have to go through a 64k aperture), it would be
// beneficial to create the surface via EngCreateBitmap, giving GDI a
// pointer to the framebuffer bits. When we pass a call on to GDI
// where it can't directly read/write to the surface bits because the
// surface is device managed, it has to create a temporary bitmap and
// call our DrvCopyBits routine to get/set a copy of the affected bits.
// For example, the OpenGL component prefers to be able to write on the
// framebuffer bits directly.
