[SDL] Windows Platform issues

Any reason to want to link SDL statically? I can see the logic if the
program is a single file, but I doubt The Cave is the case. Then
again, there isn't any reason why it shouldn't work, so this should be
checked. Sadly, I only used MinGW, not Visual Studio, so I don't think
I can help much here.

What webcam reported itself as a controller? o_O;

And if I recall correctly, Direct3D is the *default* for SDL on
Windows. You can override what renderer gets used with
SDL_SetHintWithPriority (and setting the hint to override). This is
for SDL renderers though, for which you wouldn't be using
system-specific APIs at all in the first place.

SDL has code to initialize OpenGL without a renderer, I don't think it
has for DIrect3D, but you could still initialize Direct3D directly
right after creating the window if you really want that. You can use
SDL_GetWindowWMInfo to get the hwnd of the SDL window.
