Simple API does not preserve EXIF metadata

[GoogleCodeExporter]

I could have missed something simple but...

Using C# and dllimport

What steps will reproduce the problem?
1. Encode Image containing EXIF info using WebPEncodeBGRA.
2. Save image using File.WriteAllBytes.

What is the expected output? What do you see instead?
Image should contain EXIF metadata, image does not.

What version of the product are you using? On what operating system?

0.4.0 Windows 7/8.1

libwebp doesn't offer metadata manipulation, a separate pass using libwebpmux 
[1] will be needed.

I'm marking this as an enhancement for tracking, but closing it as there aren't 
any plans to add this functionality to libwebp currently.
