cc6fcbfc09 cssfiltervalue: Fix blur filter interpretation 
According to https://www.w3.org/TR/filter-effects-1/,
the length passed to blur() is the standard deviation,
and according to https://www.w3.org/TR/css-backgrounds-3/#shadow-blur
the blur radius is twice the standard deviation.

24d8c0a7dc css: Set the is_computed flag for more values 
With these changes, we skip roughly 85% of compute() calls during
widget-factory startup

31aa5a0e53 cssvalue: Add is_computed flag 
When a css value has "child" css values (e.g. a linear gradient has
several color stop css values) which are all computed (won't change when
compute() is called on them), we want to skip computing the entire
subtree.

Since css values are immutable, we can set the is_computed flag at
construct time.

Since GtkCssValue instances are 0-initialized in _gtk_css_value_alloc,
the default for is_computed it FALSE. This commit only sets it to TRUE
in a few cases, such as various "none" singleton values which will never
change. Later commits will refine this and set it for more values.

the individual css value types

message.

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.

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.

86c60592fb css: Implement the blur filter 
This implementation is somewhat incomplete, since
we don't allow combining blur with the other filters
yet.

b58de2d16c snapshot: Redo pop() API 
gtk_snapshot_pop() => removed
gtk_snapshot_pop_and_append() => gtk_snapshot_pop()

So now there is no way to get a rendernode out of the snapshotting API
until you gtk_snapshot_finish().

fb43807fbb cssfiltervalue: Change node name 
We're not just using this for icon filters, but for regular filters, so
the existing name is confusing.

2645b5a7d7 gtk: Implement -gtk-icon-filter 
This uses the new GskColorMatrixNode to implement a filter that applies
to icons. It's meant to replace -gtk-icon-effect.
