The WebPWrapper class is (almost) directly from the Wrapper for WebP format in C#.
(MIT) Jose M. Piñeiro

The only changes were made are:

- the code was downgraded to syntax acceptable by the old (but still working) Visual Studio 2010 (the function GetInfo and 2 calls to it);
	
- dll for x86 was renamed to libwebp32.dll, dll for x64 was renamed to libwebp64.dll (still it is used in Free Pascal too, and there its names should be as noticed);
