guiAviBitmapCtrl Windows ONLY fix

A little disclaimer before I get into the code. This is a quick and dirty fix to the guiAviBitmapCtrl module to get it to play AVI's under Windows only (i.e. it will not compile/work on Linux or Mac). All of the below code changes are based upon the current HEAD version:

[b]In engine\gui\guiAviBitmapCtrl.h[/b]

Change the below line (11) from:

	#if !ENABLE_AVI_GUI || !ENABLE_MPG_GUI

to

	#if !ENABLE_AVI_GUI && !ENABLE_MPG_GUI

[b]In engine\gui\guiAviBitmapCtrl.cc[/b]

Change the below line (23) from:

	#define  ENABLE_AVI_GUI    0

to

	#define  ENABLE_AVI_GUI    1

Change the below line (46) from:

	#if !ENABLE_AVI_GUI || !ENABLE_MPG_GUI

to

	#if !ENABLE_AVI_GUI && !ENABLE_MPG_GUI

Replace the entire function GuiAviBitmapCtrl::sndOpen() (lines 101-117) with the below code:

bool GuiAviBitmapCtrl::sndOpen()
{
   char               fileBuffer[1024];
   Audio::Description desc;

   // Build the audio description
   desc.mVolume    = 1.0f;
   desc.mIsLooping = false;
   desc.mIs3D      = false;
   desc.mType      = 0;

   // Create the audio source
   dSprintf(fileBuffer, sizeof(fileBuffer), "%s", mWavFilename);
   mWavHandle = alxCreateSource(&desc, fileBuffer, 0);

   return (mWavHandle != NULL_AUDIOHANDLE);
}

In order to test the above changes I created a directory under fps called AVI. I then created the below script (avitest.cs) in that directory. Here is the source code to the script:

// Issue the below command at the console:
   //
   //    exec("fps/AVI/avitest.cs");
   //

   new GuiControlProfile (IntroProfile)
      {
      opaque      = false;
      fillColor   = "0 0 0";
      fillColorHL = "0 0 0";
      fillColorNA = "0 0 0";
      tab         = true;
      canKeyFocus = true;
      };

   // Create the GuiAviBitmapCtrl
   new GuiAviBitmapCtrl(IntroGui)
      {
      profile = "IntroProfile";
      horizSizing = "width";
      vertSizing = "height";
      position = "0 0";
      extent = "640 480";
      minExtent = "8 8";
      visible = "1";
      variable = "";
      helpTag = "0";
      useVariable = "1";
      aviFileName = "fps/AVI/test.avi";
      wavFileName = "fps/AVI/test.wav";
      setFirstResponder = "1";
      letterBox = true;
//      letterBox = false;
      swapRB = true;
      };

   Canvas.pushDialog(IntroGui);
   Canvas.hideCursor();
   IntroGui.play();
   schedule(100, 0, checkIntroDone);

//-----------------------------------------------------------------------------
function checkIntroDone()
{
   if (IntroGui.done)
      {
      Canvas.popDialog(IntroGui);
      Canvas.showCursor();
      IntroGui.delete();
      IntroProfile.delete();
      }
   else
      schedule(100, 0, checkIntroDone);
}

You will need to create a test AVI (test.avi) and WAV (test.wav) file and place them in the fps/AVI directory prior to executing the above script. To test the AVI control, open the console from the main menu and issue the command:

exec("fps/AVI/avitest.cs");

As far as a Linux and Mac solution, it is on my to do list (no estimate of availability at this time). The above coding changes where done to validate that the existing Windows code was functional.
