commit f7ad46993279d1da56980fc100b3961e5e349400
Author: Caolán McNamara <caol...@redhat.com>
Date: Wed Jun 15 21:05:50 2016 +0100
crashreport: 644837b5-c445-4779-a75d-dd69fc2e3a6f
drop hint of previous window to get mouse wheel event
when that window is disposed in order to drop any
references to it immediately that happens to avoid
anything else lingering too late
move the VclPtr into ImplSVData alongside the rest of the things like this
so
we can remove the static VclPtr which itself replaced a relatively harmless
static Window*
