ICC profile not copied from .TIFF

[GoogleCodeExporter]

Hi there.

I am converting .TIFF to .WEBP using this commandline: cwebp -lossless -m 6 
-metadata all sony24.tif -o sony24.webp.
At first, cwebp shows "Warning: only ICC profile extraction is currently 
supported on this platform!" - I don't know why.
The .TIFF also contains an ICC profile which does not seem to detected and 
imported.

I am using Windows 8 and WEBP 0.3.1.
The problem file is here: http://www.squeezechart.com/sony24.tif

How can I get the metadata of my .tif files to .webp during conversion and 
without using webpmux.exe after conversion?
And when can we expect a WIC codec with metadata support?

Best regards,
Stephan

The file seems to have no color profile, there is no bug.
Its just strange that EXIF and XMP metadata do not get imported on Win8 
platform - is this related to WIC or Win8? And when can we expect full support 
for metadata?

Closing this as #163 can track the reset.

This is due to a lack of implementation on the WIC side (wicdec.c); it should 
be possible if the correct interfaces are employed, but this hasn't been 
explored yet.
