Traces of gdiplus when taking a screenshot in GW1
> From reading the code, it seems the memcpy operations of wicformat have same

results on both pre-regression and post-regression code.
The only difference it that old code left gdipformat to 0 when
IsEqualGUID(&wicformat, wic_pixel_formats[i]) is false for all i, and new code
sets gdipformat = PixelFormat32bppARGB in that case.

Pleaes correct me if I'm wrong, and please take a look at trace+gdiplus of the
different versions if it helps give any idea what's wrong with the code.
