23e35706b4 gsk: Add support for rounded clip rectangles
Also add support to GtkSnapshot, so people can push rounded clips.

59d638a09f gsk: Add GskRoundedRect
It's essentially a port of GtkRoundedBox to graphene.

1f988d8b05 gsk: Add gsk_clip_node_new()
The node is a simple clipping node: It does a rectangular clip of its
contents.

07d39299ea gsk: Replace gsk_render_node_set_opacity()
... with gsk_opacity_node_new().

Also implement support for opacity in gtk_widget_snapshot() using this
new node.

e82d02432e gsk: Add gsk_render_node_draw()
Draws a node to a given cairo_t. This is mostly intended for fallback
usage.

02131d590e snapshot: Change how gtk_snapshot_push/pop works
Instead of appending a container node and adding the nodes to it as they
come in, we now collect the nodes until gtk_snapshot_pop() is called and
then hand them out in a container node.

The caller of gtk_snapshot_push() is then responsible for doing whatever
he wants with the created node.

Another addigion is the keep_coordinates flag to gtk_snapshot_push()
which allows callers to keep the current offset and clip region or
discard it. Discarding is useful when doing transforms, keeping it is
useful when inserting effect nodes (like the ones I'm about to add).

67fb129ed7 gsk: gsk_render_node_set_transform() => GskTransformNode
Instead of having a setter for the transform, have a GskTransformNode.

Most of the oprations that GTK does do not require a transform, so it
doesn't make sense to have it as a primary attribute.

Also, changing the transform requires updating the uniforms of the GL
renderer, so we're happy if we can avoid that.

3eb7c4719b gsk: Remove gsk_render_node_set_bounds()
gsk_render_node_get_bounds() still exists and is computed via vfunc
call:
- containers dynamically compute the bounds from their children
- surface and texture nodes get bounds passed on construction

e4ee65fd19 gsk: Remove gsk_render_node_set_opaque()
If we ever feel, we need this function again, we can readd it later.

But nobody is using it other than for overriding opactiy. And you can
just override opacity directly if you care.

a97b819b81 gsk: Add gsk_container_node_new()
It replaces gsk_renderer_create_render_node() which was doing the eact
same thing, only taking an unused extra argument.

cb5c5170f4 gsk: Remove unneeded children modifiers
Creating render nodes is fire-and-forget, so all one should do is create
a container, append, append, append and then send it off to the
renderer. So there's no need to replace, insert between or anything
else.

60567db486 gskrenderer: Add gsk_renderer_begin_draw_frame()

processing before passing it on to GDK.

e42e27304a gskrenderer: Store the GL context
And use it to create the drawing context with it.

Note that this doesn't yet have any effect and is all infrastructure
preparation work.

5563841603 gsk: Add gsk_renderer_new_for_window()
and remove gsk_renderer_get_for_display().

This new function returns a realized renderer. Because of that, GSK can
catch failures to realize, destroy the renderer and try another one.

Or in short: I can finally use GTK on Weston with the nvidia binary
drivers again.

ce98df881f gsk: Change gsk_renderer_realize()
Instead of having a gsk_renderer_set_window() call, pass the window to
realize(). This way, the realization can fail with the wrong window.

e201c4dc92 gsk: Remove gsk_render_node_get_scale_factor()
Scale factors belong to the renderers, not the nodes. The nodes should
just use whatever scale factor the renderer tells them to when
rendering.
