user: handle special cases for SPI_SETDESKWALLPAPER

The special cases remove the wallpaper or set it to default.  
Previously, these cases were ignored, so Wine would crash.







 
-if (filename == (LPSTR)-1)

+if ((LPCSTR)SETWALLPAPER_DEFAULT == filename || (LPCSTR)NULL == filename 
|| '\0' == filename[0])
 {
-   GetProfileStringA( desktop, WallPaper, (None), buffer, 256 );
-   filename = buffer;
+   /* set default wallpaper or remove wallpaper*/
+   if (hbitmapWallPaper)
+   DeleteObject( hbitmapWallPaper );
+   return TRUE;
 }
 hdc = GetDC( 0 );


According to MSDN, if
 - pvParam==SETWALLPAPER_DEFAUL || pvParam==NULL, then wallpaper will 
be set to default one

- pvParam[0]=='\0', then wallpaper will be removed.
I cannot see any signs of such distinction in your code :)

When I ran the unit test on Windows 2000, that's what it did: in all 
three cases (SETWALLPAPER_DEFAULT, NULL, or '\0'), Windows 2000 removed 
the wallpaper.  So, it seems the default wallpaper is no wallpaper, and 
a test could be added to show that.  (I already have a test that checks 
the default wallpaper is the same on both SETWALLPAPER_DEFAULT and NULL).


Beyond the cosmetics of changing the wallpaper, the purpose of the new 
code is to keep Wine from crashing on SETWALLPAPER_DEFAULT.
