Creating video surfaces

How about:

dxsd.ddsCaps.dwCaps = DDSCAPS_TEXTURE | DDSCAPS_VIDEOMEMORY | DDSCAPS_SYSTEMMEMORY;

Will try to use video memory first, and if that fails then it will use system memory.

If the call is done ONLY with DDSCAPS_VIDEOMEMORY and that fails then it should return with an error and leave it to the programmer to do what he wants (possibly use the code that you showed).

Hm. I'm not too keen on this one... It doesn't feel right to supply both flags. I've added a couple of new flags as well (local and non local video memory), so basically it could look like:

CreateSurface(GDSURFACE_VIDEOMEMORY | GDSURFACE_SYSTEMMEMORY | GDSURFACE_LOCALVIDMEM, ...)

Not too good...

Current flags are: GDSURFACE_CLEAR, GDSURFACE_NOCOORDCHECK, GDSURFACE_SYSTEMMEMORY, GDSURFACE_VIDEOMEMORY, GDSURFACE_LOCALVIDMEM, GDSURFACE_NONLOCALVIDMEM

Maybe another flag, like GDSURFACE_FALLBACKTOSYSMEM or similar? This would enable code like:

CreateSurface(GDSURFACE_VIDEOMEMORY | GDSURFACE_LOCALVIDMEM | GDSURFACE_FALLBACKTOSYSMEM, ...)

Oh yeah. Looks VERY nice to me. Also makes more sense.
