3322599e99 css: Introduce the idea of dynamic values
Dynamic values are values that change their contents with the current
(monotonic) time.

This just introduces the GtkCssValue API for it.

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.

20fc576275 gtk/gtkcssenumvalue.c: Deal with __builtin_popcount on MSVC
__builtin_popcount is a GCCism that is used to count the number of bits
involved, which means any non GCC/CLang compilers won't like the code,
meaning that on MSVC builds we must implement it ourselves.

We first use __cpuid() to check whether the CPU supports the popcount
instruction, if it does, we use the __popcnt intrinsic, otherwise
(untested, since I don't have a system that does not have the
instruction), we use the suggested hacks at
http://graphics.stanford.edu/~seander/bithacks.html#CountBitsSetParallel

6859f0a6d1 css: Use enums instead of idents for font-variant properties
As Benjamin says, ident should only be used if any value
is valid, which is not the case here. So use enums instead,
which should also be more efficient. To handle the more
complicated cases like font-variant-ligatures, we have to
introduce flags-like values.

92398bb1bb css: implement font-variant as a shorthand
Drop the current css2-style font-variant property and
replace it with a shorthand as specified in the css3 fonts
module. Currently, we fully support the font-variant-ligatures,
font-variant-position, font-variant-caps, font-variant-numeric
and font-variant-east-asian subproperties. font-variant-alternatives
is only partially supported.

60982265fa css parser: Fix names for blend modes
When the blend modes were ported to use gsk defines, some
dashes were accidentally turned into underscores. It also
turns out that we were expecting 'saturate' instead of
'saturation' as per the css spec. Fix that as well.

45957100b0 Revert a mistaken change
I thought I needed ot rearrange the ordering of the animation-direction
values for the parser, overlooking the fact that we already parse them
backwards to address this very problem.

3c4be3c912 Fix parsing of some css properties
Our property parser stops at the first match when looking for
enums, so we need to order our values so that we don't end up
with prefixes of longer names being found first.

I noticed this when the parser tried to interpret
background-blend-mode: color-burn; as "color, with junk at the end".

It also affects animation-direction, which is also fixed here.

369db4a406 css: add background-blend-mode support
CSS supports blend modes, in which a series of layers are
merged together according to the given operation or set of
operations.

Support for blend modes landed on Cairo, which exposes all
the commons and also the exquisites blend modes available.
Adding support for blend modes, then, is just a matter of
using the available Cairo operations.

This patch adds the background-blend-mode CSS enum property,
and adapts the background rendering code to blend the backgrounds
using the available blend modes when they're set.

309c6dfaf8 css: Use setters for font size and family

df08fc91bd css: always get default font size in pixels
Fixes a couple bugs...

 - Pixel font sizes in css would render as point sizes.

 - For em font sizes, where the parent size was set and not default, we would
   incorrectly convert a pixel value from points to pixels.

We'll always grab the default font size in pixels so we don't keep confusing
things.

Worth noting that gtk css font-size will still behave differently than the
web. Pango interprets font-size differently.

5ad60caa3c css: Implement font-stretch
The font-stretch CSS property is defined in the Level 3 CSS Fonts
module, available at:

  http://dev.w3.org/csswg/css-fonts/#propdef-font-stretch

It allows defining a normal, condensed, or expanded face to the font
description. Pango already supports it, so this is literally just the
CSS parser machinery needed to bridge our CSS to the FontDescription
API.

109fcb987b css: Add a -gtk-icon-style property
The values can be:
  "requested" - the style as requested
  "regular"   - use a regular full-color icon
  "symbolic"  - use a symbolic icon

The property defaults to "requested", so no changes should be seen
unless CSS overrides it.
It is also inherited, so that using this CSS
  .toolbar { -gtk-icon-style: symbolic; }
is enough to force the whole toolbar to use symbolic icons.

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.

0d9d576172 css: Add more features to font-size code

all is well now.

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.

e3fc081c5d cssvalue: Pass property ID to transition function
This is to allow animating arrays properly. I'm not really thrilled
about this solution (we leak propertys into the values again...), but
it's the best I can come up with - I prefer it to having N different
array types...

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.

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.
