[PATCH] comctl32/treeview: Make textWidth in struct _TREEITEM compatible with native one.

[Zhiyi Zhang]

Hi Nikolay,

This fixes https://bugs.winehq.org/show_bug.cgi?id=35127

As I was working through bug 35127, I noticed that you had once changed 
the layout of struct _TREEITEM in commit 
6ec621e835e03f715d5fee27c5de5b0d361814de.

Now I am sure that textWidth in struct _TREEITEM is a WORD and is at the
offset 0x1a. You can check out the bug comments for details. I tried to 
find out what is at 0x18 but no luck, thus I am adding a unknown member 
to make textWidth at the right offset.

What do you think of the patch? Do you know what member is at struct 
_TREEITEM+0x18? I can use your opinion with this patch.

Thanks,
Zhiyi Zhang
