There is no apparent reason why negative spacing should not be allowed.
And in fact, you can use negative spacing to eliminate double edges
in the grid when the delegate is e.g a rectangle with a border.

Normally you either assign a model to TableView that
already has a delegate (or don't need one), like
DelegateModel or ObjectModel. Or instead you assign
a QAIM model and a delegate directly. But if you
assign both a delegate and an ObjectModel, TableView
would be confused, and ignore the assigned model
and instead create an internal wrapper model that
ends up empty.
This patch will ensure that we don't create a wrapper
model in such cases, but instead forward the
delegate to whichever model is assigned, even
if it ends up as a no-op for models that don't
use one.

problem is that this file is also used from other places
where we wrap a QSharedPointer that points to the model

a TableView, the QML binding will see the QSharedPointer, and
not the model it points to. And hence complain that the
model doesn't have the API that is exported from the
model.
The easy fix is to just create a new QML file for the
new test added, that has the binding, but assigns
a QVariant that wraps the model directly without
usign a QSharedPointer.

When reusing a delegate item, it can sometimes happen that the item
ends up being reused at the same location in the table as it had
before it was pooled. And in that case, we don't emit changes to
index, row and column since they technically didn't change.
The problem is that the model might have changed in-between, e.g if
a row has been removed. And in that case, row and column will, even
when unchanged, point to other parts of the model. So all bindings
needs to be reevaluated to ensure that the values they use are
refreshed.
This patch will therefore ensure that we always emit changes to
the mentioned properties when an item is reused, regardless if
they change or not.

The same holds true for the special properties that come from the

There are now three mechanisms in TableView that works together to
ensure that the table ends up edge-to-edge with the content view. They
are applied in the following order:
1. Adjust the content size, based on the predicted size of the table.
2. Adjust the origin and endExtend on the fly, if the content size is wrong.
3. Move the table directly to where it should be, in case we don't have
time to wait for the origin to change.
We could have, strictly speaking, setteled with just one of them, but choose
to use them all at the same time for best flicking experience. Still, 1. and
2. sometimes step on each others feet when they both detect that something is
a bit off, and adjust.
So rather than adjusting the size of the content view every time we load a
new row or column, we just keep the first prediction. And then we leave all
later ajustments to 2. and 3. This turns out to be a more stable, and will
avoid some glitches that occur when flicking using a scrollbar, if several
mechanisms kick in at the same time.

We set the size of the content view to be the size of the complete
table. The problem is that the exact size will always be just
a prediction, since we would otherwise need to iterate over all rows
and column up front, to be able calculate the exact size.
This is not acceptable when using non-trival table models.
A side effect of this, is that is will be possible to flick the
viewport further out than the actual end of the table, if the
content view turns out to be larger than the table itself. From
before we used to just move the whole table back into the viewport
when that happened, which could be seen as a sudden jump of the
table to a new position.
This change will improve this logic so that we can avoid most
visual jumps. Instead of moving the table around, QQuickFlickable
supports moving the origin instead. So when we see that the
table is not in sync with the content view, we simple move the
origin to the edge of the table. The effect is that any flicking
or ongoing momentum animation in QQuickFlickable will continue as
if nothing happened. This is also the same logic used by QQuickListView.

TableView keeps track of which rows and columns that are loaded
at any point by using a QRect called "loadedTable". loadedTable
basically describes the top-left and bottom-right corner of the
table that has been loaded (which also is what ends up visible
on screen).
But now that we prepare for making it possible to hide rows
and columns, using just a QRect becomes to simple. A rectangle will
only tell what the edges of the table are, but not if any of the
rows and columns in-between are hidden and therefore not loaded.
So a QRect(0, 0, 10, 10) will give us the impression that we have
10 visible columns on screen, but in reality, we might have a
lot less.
This patch will change this to instead use two QMaps to record
loaded rows and columns. This will make it much more easy
to deal with hidden rows and columns in upcoming patches. We
use a QMap instead of a QHash/QSet to keep the list of columns and
rows sorted, since we frequently still need to know the edges of
the table, like before.

When flicking, the current implementation would load and unload
edges around the table until the new viewport was covered. The downside
of that strategy is that you if you move the viewport a long
distance in one go, you will need to load and unload edges hidden
outside the viewport until it catches up with the new viewport. It gets
even worse if you flick with a scrollbar, since then you can end up
flicking thousands of rows in one go. And this will keep tableview
busy loading and unloading edges for a "long" time.
This patch will fix this issue by checking how much the viewport
changes during a flick, and select a strategy based on that. So if the
viewport moves more than a page (which is the size of the viewport), it
will schedule a rebuild of the table from the viewports new location,
rather than trying to load and unload edges until it catches up.

componentComplete() is called on us after all static values
have been assigned, but before bindings to any ancestors
have been evaluated. Especially this means that if our size
is bound to the parents size, it will not be ready at that point.
Since we cannot build the table without knowing our own size, we
waited for the updatePolish() call before we started to build
the table.
The problem with that strategy, is that any asynchronous loaders that
TableView might be inside would already be finished by the time
we received the updatePolish() call. The result would be that we
ended up loading all the delegate items synchronously instead of
asynchronously. (As soon as a loader has finished loading the initial
item, async loading will no longer be used).
This patch will therefore add a componentFinalized function that gets
called after all bindings have been evaluated, but before the loader
has finished. When receiving this call, we load the delegate items (and
build the table).
A nice side effect is that the table will also be ready
by the time Component.onCompeted is emitted to the QML
app. This means that e.g contentWidth/Height has valid values.

Overriding contentWidth/Height was done to be able to force build the
table early if the app needed to know the size of the table already at
Component.onCompleted (to e.g center the viewport on the center of
the table). But now that we have a forceLayout() function, it's better
to require that that function should be called before querying
contentWidth/Height at this stage.
By not building the table on the fly, we allow the application to
bind expressions directly to contentWidth/Height, without being concerned
about potential binding loops that can occur as a result of us
rebuilding the whole table behind his back. The benefit of this overshadows
the need to call forceLayout() explicit for some corner cases.
Note that we still redefine the contentWidth/Height properties in TableView
so that we can catch if the application sets an explicit contentWidth/Height
(which is tested by checkExplicitContentWidthAndHeight()).
