Set up a video mode with the specified width, height and bits-per-pixel.
If bpp is 0, it is treated as the current display bits per pixel.
The flags parameter is the same as the flags field of the SDL_Surface structure. OR'd combinations of the following values are valid.
Create the video surface in system memory
Create the video surface in video memory
Enables the use of asynchronous to the display surface. This will usually slow down blitting on single CPU machines, but may provide a speed increase on SMP systems.
Normally, if a video surface of the requested depth (bpp) is not available, SDL will emulate one with a shadow surface. Passing SDL_ANYFORMAT prevents this and causes SDL to use the video surface, regardless of its depth.
Give SDL exclusive palette access. Without this flag you may not always get the the colors you request with SDL_!SetColors?.
Enable double buffering. Calling SDL_Flip will flip the buffers and update the screen. If double buffering could not be enabled then SDL_Flip will just perform a SDL_!UpdateRect? on the entire screen.
SDL will attempt to use a fullscreen mode
SDL_OPENGL Create an OpenGL rendering context. You should have previously set OpenGL video attributes with SDL_GL_!SetAttribute?.
Create an OpenGL rendering context, like above, but allow normal blitting operations.
Create a resizable window. When the window is resized by the user a SDL_VIDEORESIZE event is generated and SDL_!SetVideoMode? can be called again with the new size.
