These are always set to the same value as the corresponding border
radius properties. They are also non-standard, so remove them and
replace them with the border radius properties everywhere.
Fixes#2414
When we are loading symbolic pngs or svgs, we know
that we need to the png or svg loader, so there is
no need to go through (surprisingly expensive) mime
sniffing to find the right loader.
It doesn't really make sense to treat double clicks here different than
single clicks (and is bad UX), and it also breaks switching months by
quickly trying to single-click the last/first days in the calendar.
This is an unused feature that's way too complicated for a default
calendar widget and complicates the implementation a lot. Since we want
to eventually replace this with actual widgets, remove the details
support now.
These will replace the previous gtk_snapshot_new_with_parent(), which
allocated an entirely new GObject just to push()/pop() some state. This
is already a problem but will be more important in the future as we
start using this more.
When reaching this point, it is impossible that all border styles are
HIDDEN or NONE, but up to 3 of them can still be that style. In any
case, the "none or solid" border style is the most common on there is,
so try to make this simpler here by just appending a border node
directly instead of going through the snapshot_border path.
Hide the expensive GTK_IS_ROOT() checks behind the cheaper realized,
mapped, etc. checks. This way we only check for the widget being a root
if the invariant does not hold.
This gets pop_verify_invariants() from 16% to 6% when running the
scrolling benchmark in the widget-factory.
If there is a passive grab and the pointer leaves the window we would
receive a GDK_CROSSING_NORMAL event when the pointer moves outside
the window, and a GDK_CROSSING_UNGRAB event when we do release the
button and the implicit grab.
We currently would react to the first, but want to react to the
second. In the time between both events, the client would still receive
pointer motion that will reach the implicitly grabbed widget.
