Currently, in git master, you can get the min and max (white and black,
I intend to fix that when I really break the API), the color matrix
(from DNG).
The interesting commit for color matrices is here:
<http://cgit.freedesktop.org/libopenraw/commit/?id=7608d4416b4aabfb5863a7769805a2b400f4bdb0>

The problem is that several of these are hard coded for each model, so
the need to be added one by one.

My goal right now is to have all the info needed to properly process the
RAW to a sRGB, including camera multipliers, etc.

I'm open to suggestions, improvements, etc.

But right now it is too early in the cycle to even promise a stable API,
but it is getting there slowly.

Hope that helps,
