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.
|SDL_SWSURFACE||Create the video surface in system memory|
|SDL_HWSURFACE||Create the video surface in video memory|
|SDL_ASYNCBLIT||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.|
|SDL_ANYFORMAT||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.|
|SDL_HWPALETTE||Give SDL exclusive palette access. Without this flag you may not always get the the colors you request with SDL_SetColors.|
|SDL_DOUBLEBUF||Enable double buffering; only valid with SDL_HWSURFACE. 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_FULLSCREEN||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.|
|SDL_OPENGLBLIT||Create an OpenGL rendering context, like above, but allow normal blitting operations.|
|SDL_RESIZABLE||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.|
|SDL_NOFRAME||If possible, SDL_NOFRAME causes SDL to create a window with no title bar or frame decoration. Fullscreen modes automatically have this flag set.|
Note: Whatever flags SDL_SetVideoMode could satisfy are set in the flags member of the returned surface.
