Does this code actually work for you?

First of all, when creating a BitmapFrame with PreservePixelFormats the
ColorContext is *always* nill!!!
It does not work for me, with the JPEG files I tried.

I would *love* for the ColorContext to come across as I would be able to
create an ICC profile from memory, the way to do it.
It is perfect! Except, it does not work.

In all my testing, so far, I have NOT been able to retrieve a ColorContext
(embedded ICC profile) from a JPEG image.

Second question...

Where does the "StreamToArray" method comes from?
