00aa4f0597 cssimagelinear: Use count+array for the color stops, not GArray
This makse sense but will also make later changes to GtkCssImageLinear
simpler.

67991ed0f4 Remove GtkCssRgbaValue
The differenciation between a literal color value and an RGBA value
caused problems in various situations. Just treat the two the same but
don't allow access to the rgba value of a non-literal color value.

This gets rid of around 1.6k rgba values in the widget-factory.

We handlet the common easy cases manually anyway, so don't bother
sqrt()ing the x/y coords in those cases.

73b4a62f51 snapshot: Redo debug messages
Instead of every snapshot function having debug messages, have an
explicit gtk_snapshot_push_debug() function that appends a debug node.

19871cfd68 snapshot: Add & use API for linear gradient nodes
This way, we can also clip the created node bounds to the current clip
of the GtkSnapshot. This works as long as we don't modify the start and
end points, and happens all the time while rendering.

83fb7a649f css: Merge GtkStyleProviderPrivate into GtkStyleProvider
This is just lots of renaming.

The interface remains private, so the public API does not change, apart
from removing the definition of the Interface object to avoid
subclassing.

Instead of having gtk_snapshot_append_foo_node(), just have
gtk_snapshot_append_foo(). Nobody needs to know that this internally
uses nodes.

c00f8dce9f GtkSnapshot: Always use int for the translation
We already take ints when setting the translation, so it can't
currently take any other values. Additionally, I was seeing large
costs in int -> double -> int for the rects in
gtk_snapshot_clips_rect(), as all callers really are ints (widget
allocations) and the clip region is int-based.

This change completely cleared a 2% rectangle_init_from_graphene from
the profile and is likely to have nice performance effects elsewhere
too.

599cc995f3 css: Handle repeating gradients with only one offset
Example:
  repeating-linear-gradient(red 50%, blue 50%)

Those gradients in Firefox draw a solid image of the last color, so do
the same here.

23edff1606 gtkcssimagelinear.c: Avoid VLAs
VLAs are not supported by Visual Studio and possibly other compilers that
are supported by GTK+-3.90+, and probably never will be, although it is a
C99 specification, and it became optional for C11.  It is also not a part
of the newer compiler requirements that are listed out for GTK+-3.90.x.

There exist concerns about the implementation of VLAs in compilers that
support them as well, so change it to a g_newa() approach.

519af3f91d cssimage: Warn if gradients only have 1 color stop
GTK <= 3.20 allowed that but the CSS spec and borwsers do not.

a7e2a9d8d3 Don't interpolate between keywords
Transitioning between linear gradients like
linear-gradient(to top, yellow, green) and
linear-gradient(to left, yellow, green) was yielding
nonsensical results, with the gradient line jumping around
wildly. Fix this by falling back to stupid image interpolation
for these cases.

This way, we can remove it as a separate argument from

thing: the style provider.

af2c40bd54 css: Add a scale argument to css-value compute vfunc
We need to be able to compute different GtkCssImage values
depending on the scale, and we need this at compute time so that
we don't need to read any images other than the scale in used (to
e.g. calculate the image size). GtkStyleProviderPrivate is shared
for all style contexts, so its not right.

1454ba15ba css: Huge refactoring to avoid computing wrong values
Here's the shortest description of the bug I can come up with:
When computing values, we have 3 kinds of dependencies:
(1) other properties ("currentColor" or em values)
(2) inherited properties ("inherit")
(3) generic things from the theme (@keyframes or @define-color)
Previously, we passed the GtkStyleContext as an argument, because it
provided these 3 things using:
(1) _gtk_style_context_peek_property()
(2) _gtk_style_context_peek_property(gtk_style_context_get_parent())
(3) context->priv->cascade

However, this makes it impossible to lookup values other than the ones
accessible via _gtk_style_context_peek_property(). And this is exactly
what we are doing in gtk_style_context_update_cache(). So when the cache
updates encountered case (1), they were looking up the values from the
wrong style data.

So this large patch essentially does nothing but replace the
context argument in all compute functions with new arguments for the 3
cases above:
(1) values
(2) parent_values
(3) provider

We apparently have a lot of computing code.

0e2f35ed88 css: Introduce dependencies for value computations
When values are computed, they might depend on various other values and
we need to track this so we can update the values when those other
values change. This is the first step in making that happen.

This patch does not do any dependency tracking at all, instead it uses
GTK_CSS_DEPENDS_ON_EVERYTHING as a sort of FIXME.

09f9fd42b4 css: Fold color value computation into gtksymboliccolor.c
This gets rid of the public function
_gtk_css_rgba_value_compute_from_symbolic().
The fallback is now handled using a switch statement instead of letting
the caller pass the function.

9b4ed66218 css: Pass property_id to compute function
This is a reorganization of how value computing should be done.
Previously the GtkCssStyleProperty.compute vfunc was supposed to take
care of special cases when it needed those for computation. However,
this proved to be very complicated in cases where values were nested and
only the last value (of a common type) needed to be special cased.

A common example for this was the fallback handling for unresolvable
colors.

Now, we pass the property's ID along with all compute functions so we
can do the special casing where it's necessary.
Note that no actual changes happen in this commit. This will happen in
follow-ups.

9b953829fb css: Introduce _gtk_css_value_compute()
This commit is essentially a large reorganization. Instead of all value
subtypes having their own compute function, there is the general
_gtk_css_value_compute() function that then calls a vfunc on the
subtype.
