Thanks Nikolay and Zhiyi - sorry this patch was no good, I'm new to
Wine and got a bit excited when I saw Cut2D doing the right thing.

I have written some conformance tests to show the underlying issue is
that when columns are reordered, subitem hittesting
(LVM_SUBITEMHITTEST) returns different results on Windows, and
invalidation doesn't calculate the right bounds.

Working on a new patch set, hoping to find some time in the next
couple of days to send it.
