Workaround for Image.FromStream(tmpStream); in Webplayer for gif files

Hi!

This works in the Unity Editor, but when I compile it in Webplayer plattform and open it in firefox, I get the Error, that System.Runtime.InteropServices.ComTypes.IStream namespace is not available. So Webplayer not supports several namespaces in System.Drawing.dll. This line throws an exception: var gifImage = Image.FromStream(tmpStream); Can anyone give me a workaround for that? I guess I need a parser to convert bytes into an Image instance.

Full souce code:

 /// <summary>
 /// Loads the image via WWW class.
 /// </summary>
 /// <returns></returns>
 /// <param name="path">Path.</param>
 IEnumerator LoadImageWWW(string path) {
     // Start web request
     WWW req = new WWW (ConvertToUrlFriendly(path));
     // Wait for answer
     yield return req;
     // Did an error appear during loading?
     if (req.error != null)
         // Log error and skip this file
         Debug.LogError (req.error);
     else {
         // Creates Stream
         MemoryStream tmpStream = new MemoryStream(req.bytes);
         // Initialize gif function
         var gifImage = Image.FromStream(tmpStream);
         drawPosition = new Vector2 (centerPosition.x-gifImage.Width/2.0f,centerPosition.y-gifImage.Height/2.0f);
         var dimension = new FrameDimension(gifImage.FrameDimensionsList[0]);
         int frameCount = gifImage.GetFrameCount(dimension);
         for (int i = 0; i < frameCount; i++)
         {
             gifImage.SelectActiveFrame(dimension, i);
             var frame = new Bitmap(gifImage.Width, gifImage.Height);
             System.Drawing.Graphics.FromImage(frame).DrawImage(gifImage, Point.Empty);
             var frameTexture = new Texture2D(frame.Width, frame.Height);
             for (int x = 0; x < frame.Width; x++)
                 for (int y = 0; y < frame.Height; y++)
             {
                 System.Drawing.Color sourceColor = frame.GetPixel(x, y);
                 frameTexture.SetPixel(x, frame.Height -1 - y, new Color32(sourceColor.R, sourceColor.G, sourceColor.B, sourceColor.A)); // for some reason, x is flipped
             }
             frameTexture.Apply();
             gifFrames.Add(frameTexture);
         }
     }
 }

Thank you in advance!
