Handle it like discrete scrolling instead.

Signed-off-by: Alexander Mikhaylenko <alexm@gnome.org>

Support scrolling on devices like mice. Switch a page when a scroll event
arrives and add a delay to prevent too fast scrolling.

Use animation duration as a delay, but don't let it go below 250ms, mainly
to ensure it still works with animations disabled.

This adds a page to demo the leaflet transitions, drops usage of the
deprecated leaflet transition types and properties, and defaults to the
'over' transition to demo it and its shadow effect.

Adrien Plazas authored Nov 04, 2019 and Adrien Plazas committed Nov 23, 2019

There is no point in adding enum values and deprecating them in the same
version, so let's just remove them. The animations are still available
via the newly added HdyLeafletTransitionType type and the
transition-type property, so this also encourages migrating to the new
API.

Adrien Plazas authored Oct 29, 2019 and Adrien Plazas committed Nov 23, 2019

Add the HdyLeafletTransitionType enumeration and the transition-type
property to define both the mode and child transitions, as having them
different makes no sense and could lead to spatialization issues.

This new type doesn't offer a crossfade transition on purpose as it was
deemed inappropriate for the leaflet, for which the position of the
children is inherently important.

This also deprecates the two previous properties and their respective
types.

Fixes Librem5/libhandy#92.

Draw a dimming layer and a drop shadow over bottom child during 'over' and
'under' mode and child transitions.

The dimming, shadow and border styles are defined in CSS. The current style
is based on the similar animation in WebKit.

Adjust width and height of the clip rectangle to avoid drawing areas

This allows the mode transition animation to match the semantic of the
over and under child transitions.

Sets the children padding of the folding sliding animation depending on
the surface they'll be drawn on.

This doesn't change a thing for the sliding animation, but this will
avoid the children to be moved when snapshotting them, which is needed
for the over and under animations — which will be added in the next
commit — to work correctly.

This will clip the end surface to ensure it doesn't get drawn on or
under the visible child, which will allow to create mode transition
animations where other children appear to be drawn under the visible
child.

It's considered HdyDialer internal API

The macros are libhandy internal (should not be used in application
code) and are as such marked with a '_'. This also makes gtk-doc
happy since it treats it as a public symbol otherwise.
