Initial implementation of GSK rendering pipeline GSK is conceptually split into two scene graphs: * a simple rendering tree of operations * a complex set of logical layers The latter is built on the former, and adds convenience and high level API for application developers. The lower layer, though, is what gets transformed into the rendering pipeline, as it's simple and thus can be transformed into appropriate rendering commands with minimal state changes. The lower layer is also suitable for reuse from more complex higher layers, like the CSS machinery in GTK, without necessarily port those layers to the GSK high level API. This lower layer is based on GskRenderNode instances, which represent the tree of rendering operations; and a GskRenderer instance, which takes the render nodes and submits them (after potentially reordering and transforming them to a more appropriate representation) to the underlying graphic system.

* #GskRenderer is a class that renders a scene graph defined via a
* tree of #GskRenderNode instances.
*
gsk: Fold gsk_renderer_begin_draw_frame() into renderer It doesn't need to be exported anymore. As a side effect, the inspector no longer has any information about the render region, so remove the code that was taking care of that.

build: Enable -Wswitch-enum and -Wswitch-default This patch makes that work using 1 of 2 options: 1. Add all missing enums to the switch statement or 2. Cast the switch argument to a uint to avoid having to do that (mostly for GdkEventType). I even found a bug while doing that: clearing a GtkImage with a surface did not notify thae surface property. The reason for enabling this flag even though it is tedious at times is that it is very useful when adding values to an enum, because it makes GTK immediately warn about all the switch statements where this enum is relevant. And I expect changes to enums to be frequent during the GTK4 development cycle.

gsk: Rework GskRenderer and GskRenderNode semantics This commit changes the way GskRenderer and GskRenderNode interact and are meant to be used. GskRenderNode should represent a transient tree of rendering nodes, which are submitted to the GskRenderer at render time; this allows the renderer to take ownership of the render tree. Once the toolkit and application code have finished assembling it, the render tree ownership is transferred to the renderer.

Initial implementation of GSK rendering pipeline GSK is conceptually split into two scene graphs: * a simple rendering tree of operations * a complex set of logical layers The latter is built on the former, and adds convenience and high level API for application developers. The lower layer, though, is what gets transformed into the rendering pipeline, as it's simple and thus can be transformed into appropriate rendering commands with minimal state changes. The lower layer is also suitable for reuse from more complex higher layers, like the CSS machinery in GTK, without necessarily port those layers to the GSK high level API. This lower layer is based on GskRenderNode instances, which represent the tree of rendering operations; and a GskRenderer instance, which takes the render nodes and submits them (after potentially reordering and transforming them to a more appropriate representation) to the underlying graphic system.

Initial implementation of GSK rendering pipeline GSK is conceptually split into two scene graphs: * a simple rendering tree of operations * a complex set of logical layers The latter is built on the former, and adds convenience and high level API for application developers. The lower layer, though, is what gets transformed into the rendering pipeline, as it's simple and thus can be transformed into appropriate rendering commands with minimal state changes. The lower layer is also suitable for reuse from more complex higher layers, like the CSS machinery in GTK, without necessarily port those layers to the GSK high level API. This lower layer is based on GskRenderNode instances, which represent the tree of rendering operations; and a GskRenderer instance, which takes the render nodes and submits them (after potentially reordering and transforming them to a more appropriate representation) to the underlying graphic system.

Initial implementation of GSK rendering pipeline GSK is conceptually split into two scene graphs: * a simple rendering tree of operations * a complex set of logical layers The latter is built on the former, and adds convenience and high level API for application developers. The lower layer, though, is what gets transformed into the rendering pipeline, as it's simple and thus can be transformed into appropriate rendering commands with minimal state changes. The lower layer is also suitable for reuse from more complex higher layers, like the CSS machinery in GTK, without necessarily port those layers to the GSK high level API. This lower layer is based on GskRenderNode instances, which represent the tree of rendering operations; and a GskRenderer instance, which takes the render nodes and submits them (after potentially reordering and transforming them to a more appropriate representation) to the underlying graphic system.

gsk: Add the ability to create fallback renderers While porting GTK to GskRenderer we noticed that the current fallback code for widgets using Cairo to draw is not enough to cover all the possible cases. For instance, if a container widget still uses GtkWidget::draw to render its children, and at least one of them has been ported to using render nodes instead, the container won't know how to draw it. For this reason we want to provide to layers above GSK the ability to create a "fallback" renderer instance, created using a "parent" GskRenderer instance, but using a Cairo context as the rendering target instead of a GdkDrawingContext. GTK will use this inside the gtk_widget_draw() implementation, if a widget implements GtkWidgetClass.get_render_node().
