[SDL] Still get SDL window with SetVideoMode(0,0,0,SDL_SWSURFACE)

[manmach]

I have a wxWidgets application that uses SDL for image processing, but not
for output.

So in order not to have an SDL window, I would call
SDL_SetVideoMode(0,0,0,SDL_SWSURFACE). Or leave it out altogether, which
seemed to work too.

I could then create surfaces and overlays and have blit them to my wxWidgets
controls.

But now that I have upgraded to 1.2.12, I get an SDL window of the current
desktop size if I call SDL_SetVideoMode as in agreement with the changes
introduced with 1.2.10.

And if I leave it out, I get no window, but then SDL_DisplayYUVOverlay
fails, presumably because it clips the rectangle to the screen area, which
is absent.

If have verified this by removing the lines from SDL_yuc.c that check for
screen height and width. Without these lines I can use SDL without calling
SDL_SetVideoMode and have SDL_DisplayYUVOverlay work too.

I am sure there might be unwanted side effects, so I leave it up to you
experts to point me to a better solution.

Please advise.
