1177// This function derives and creates a GDI surface from the specified
1178// DirectDraw surface.
1179//
1180// Parameters
1181// pDirectDraw-----Points to a DD_DIRECTDRAW_GLOBAL structure that describes
1182// the DirectDraw object.
1183// pSurface--------Points to a DD_SURFACE_LOCAL structure that describes the
1184// DirectDraw surface around which to wrap a GDI surface.
1185//
1186// Return Value
1187// DrvDeriveSurface returns a handle to the created GDI surface upon success.
1188// It returns NULL if the call fails or if the driver cannot accelerate GDI
1189// drawing to the specified DirectDraw surface.
1190//
1191// Comments
1192// DrvDeriveSurface allows the driver to create a GDI surface around a
1193// DirectDraw video memory or AGP surface object in order to allow accelerated
1194// GDI drawing to the surface. If the driver does not hook this call, all GDI
1195// drawing to DirectDraw surfaces is done in software using the DIB engine.
1196//
1197// GDI calls DrvDeriveSurface with RGB surfaces only.

1200// same size and format as that of the DirectDraw surface. Space for the
1201// actual pixels need not be allocated since it already exists.
