Removed distinction between "available" and "init" in audio backends, since both had to be checked for success as a pair at the higher level and several of the Available methods were just always-succeed placeholders anyhow. Now the availability check is done in the init code, and the higher level tries all possible drivers until one manages to initialize successfully.

>The system window manager event contains a pointer to system-specific 
information about unknown window manager events.  If you enable this event
using 
<A
HREF="sdleventstate.html"
><TT
CLASS="FUNCTION"
>SDL_EventState()</TT
></A
>, 
it will be generated whenever unhandled events are received from the window 
manager.  This can be used, for example, to implement cut-and-paste in your 
application.

<PRE
CLASS="PROGRAMLISTING"
>typedef struct {
         Uint8 type;   /* Always SDL_SYSWMEVENT */
         SDL_SysWMmsg *msg;
 } SDL_SysWMEvent;</PRE
>

If you want to obtain system-specific information about the window manager,
you can fill the version member of a <SPAN
CLASS="STRUCTNAME"
>SDL_SysWMinfo</SPAN
> 
structure (details can be found in <TT
CLASS="FILENAME"
>SDL_syswm.h</TT
>, which must be included) using the <TT
CLASS="FUNCTION"
>SDL_VERSION()</TT
> macro found in 
<TT
CLASS="FILENAME"
>SDL_version.h</TT
>, and pass it to the 
function:
