075a0ccb5e renderbackground: Save a snapshot_translate() call 
Just add the values manually when really using the snapshot later. Also
unifies the two if branches by pulling out getting the x/y values.

c44c44ee25 css: Pass boxes to the render functions 
Instead of style + rect_of_one_box, pass the new GtkCssBoxes object.
This has the nice side effect that when drawing background + border +
outline, we only compute all the boxes we need once.

19ffb40b27 cssboxes: Introduce 
Split out the code for computing CSS boxes from given variables from the
background render code. This way, it can be shared between different
codebases.

Also, make that code completely be contained of static inline functions.
That ensures that it can be 100% inlined in cases where only parts of
the rectangle are needed (like in gtk_widget_get_width() in the future).

This will require some more patches to actually work, but those will
follow.

14408b7485 render: Make gtk_render_background() use the snapshot API 
This removes a lot of duplicated code.

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.

31974e02ca renderbackground: Avoid excess css value lookups 
We iterate over all background layers twice, so only lookup blend mode
vlaues once.

c9e6fcd5fa renderbackground: Pull out a gdk_rgba_is_clear check 
We only call snapshot_color once, and this way it's clearer that nothing
will happen for a clear color from the caller side.

99026d2df8 renderbackground: Minimize style lookups 
Move the early returns up so we don't look up all those css values for
no reason.

87497ca2e1 snapshot: Rename gtk_snapshot_translate_2d()

6055028c96 snapshot: Rename append APIs 
Instead of having gtk_snapshot_append_foo_node(), just have
gtk_snapshot_append_foo(). Nobody needs to know that this internally
uses nodes.

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().

not used.

b993acfe2c gsk: Add GskRepeatNode 
Also add gtk_snapshot_push_repeat() and use that to draw backgrounds.

With that change, CSS background snapshots are created without Cairo
nodes.

4d9eedafcd roundedbox: Add gtk_rounded_boxes_init_for_style() 
Instead of making people intiialize a rectangle and then applying border
radius manually, provide a constructor that does it for them.
While doing that, also allow people to instead request the padding box
or the content box.

Refactor all relevant code to use this new constructor.

071c9a8221 API: gdk: Add gdk_rgba_is_clear() and gdk_rgba_is_opaque() 
I want to use these inside GSK, and I'm not a fan of putting GdkRGBA
APIs into it or duplicating it into GTK.

So public API it is.

dd1cf1ac0f css: An opaque background does not allow omitting push_group 
When the background-clip of the background is smaller than the
background-clip of blended images, not pushing a group is wrong.

Test testing exactly that included.

f96f16899d roundedbox: Remove _gtk_rounded_box_path() 
Use gsk_rounded_rect_path() instead.

That's a private GSK function, be we can just include its header.

38f226b5ce render: Propagate snapshot drawing to box shadows 
This decouples actual background drawing from shadow drawing in the
snapshot case.

We also now create seperate nodes for shadows vs for backgrounds.

79d2d0e40d snapshot: Add gtk_snapshot_render_background() 
and gtk_snapshot_render_frame() to be direct replacements for the
old gtk_render_*() functions.

Use them to replace Cairo usage completely in gtk_window_snapshot().

a0e63b8a07 rendernode: Require passing a renderer to get_draw_context() 
This is in preparation of making render nodes independent of the
renderer, so that they can be rendered multiple times with different
renderers.

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.

CssStyle. This will become relevant in the next commit.
