15 The \fBflags\fR parameter is the same as the \fBflags\fR field of the \fI\fBSDL_Surface\fR\fR structure\&. OR\&'d combinations of the following values are valid\&.
24 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\&.
27 Normally, if a video surface of the requested depth (\fBbpp\fR) is not available, SDL will emulate one with a shadow surface\&. Passing \fBSDL_ANYFORMAT\fP prevents this and causes SDL to use the video surface, regardless of its depth\&.
33 Enable double buffering\&. Calling \fI\fBSDL_Flip\fP\fR will flip the buffers and update the screen\&. If double buffering could not be enabled then \fBSDL_Flip\fP will just perform a \fI\fBSDL_UpdateRect\fP\fR on the entire screen\&.
45 Create a resizable window\&. When the window is resized by the user a \fI\fBSDL_VIDEORESIZE\fP\fR event is generated and \fBSDL_SetVideoMode\fP can be called again with the new size\&.
48 If possible, \fBSDL_NOFRAME\fP causes SDL to create a window with no title bar or frame decoration\&. Fullscreen modes automatically have this flag set\&.
