555230ec9c Annotate more functions returning GListModel
Now that we can have an element-type annotation, we should use it where
needed.

7de62118a0 Fix message for VFL parser errors
The loop is iterating over the wrong variable, and it's reimplementing
g_strfill() in a less efficient way.

274c47e5ba constraint layout: Provide list models
Provide list models for the constraints and guides,
so we can show them in the inspector, and use them
in e.g. the constraints editor.

8ab609e4e7 Add custom parser for guides defined in GtkBuilder UI files
Like we describe constraints, we can also define guides.

6bc156c237 Implement GtkBuildable for GtkConstraintLayout
Using GtkBuildable we can provide a custom parser for reading
constraints defined in a GtkBuilder UI file.

4dd1de4129 Use explicit values for constraint strength
Instead of playing games with mapping negative symbolic values to
positive ones, let's use the appropriate constants everywhere. This
allows us to use:

        GTK_CONSTRAINT_STRENGTH_WEAK * 2

Or

        GTK_CONSTRAINT_STRENGTH_STRONG + 1

In code using the public API.

We also store the strength values as integers, so we can compare them
properly, and only turn them into doubles when they are inserted into
the solver, just like every other variable.

b224df8109 constraint layout: go back to keeping constraints
We want to minimize changes to the solver, so
keep the size constraints around and only update
them when the size changes.

c88e7c180d constraint layout: Use stronger force for min size
We want our edit constraint to be strong enough to
overpower nat. size constraint, therefore use STRONG * 2.

2aabd64f1a Fix warnings from the introspection scanner

d45a662679 Move the VFL error domain to a public header
Since the public API will use it to fill out GErrors, it needs to be
publicly available.

035baa092c Mark the layout as changed
We should mark the layout as changed when
constraints are added or removed.

9edf6fb6cb constraint layout: Dont reset constraints in allocate
If trust our allocation algorithm, this can never
trigger (and in fact, it never does).

f62fc4e2f2 constraint layout: freeze/thaw on mass ops
In measure and allocate we are potentially
changing quite a few constraints. Don't
optimize at every step.

3f36340921 constraint layout: Measure min/nat size separately
Only constraint the opposite direction if we
actually have a for_size, and measure natural
size after removing the edit constraints. With
these changes, the test that compares constraint
layout to grid layout passes.

b1f0f4478e constraint layout: Use stays for natural size
It makes more sense to treat the natural size
of both children and guides as stays, since
we want to meet these values as closely as we
can, under the circumstances.

90f8dcc5e1 constraint layout: Add debug output for guides
Print out the allocation we end up giving to
guides. This helps in making sense of the
allocations of the child widgets that these
guides relate to.

dab8a8b5c5 constraint layout: Measure more correctly
Set up all constraints for minimum + natural
width + height when measuring, regardless
of the orientation we're measuring. Anything
else will lead to incorrect answers when
there are constraints that cut across
dimensions.

139a59cae3 Flesh out GtkConstraintGuide
This commit moves GtkConstraintGuide into its own
source files to avoid gtkconstraintlayout.c turning
too messy, adds max size properties and implements
getters and setters.

60fb9092fe Drop an indirection
This struct is not really useful for just
a single hash table, and it gets in the way
of moving the guide code to its own file.

The dictionary-based function is convenient for language bindings, but C
developers will feel more at home with a variadic arguments list.

54104b6676 Fix the opposite size measurement in GtkConstraintLayout
We cannot use the given "for size" when querying our children, because
the constraint layout has no idea about the opposite size of its
children until the layout is complete.

Additionally, we should only suggest an opposite size for the layout if
we have one, instead of suggesting a weak zero size.

21450d5f23 Remove size constraints from ConstraintLayoutChild
The size constraints are transient to measurement and allocation, so
they don't really need to be stored inside the GtkLayoutChild subclass
created by a GtkConstraintLayout.

a39bbb2041 constraints: Make internal consistency required
The relations between left, right, width
and top, bottom, height are required for
internal consistency. It doesn't make sense
to ever drop these.

Changing the strength of these relations makes
my systems behave much more stable.
