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: make logging per-renderer Add a setter for per-renderer debug flags, and use them where possible. Some places don't have easy access to a renderer, so this is not complete. Also, use g_message instead of g_print throughout.

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. Signed-off-by: Emmanuele Bassi <ebassi@gnome.org>

gskrenderer: Add GError argument to gsk_renderer_realize() This way, we don't spam criticals when GL is not available. Instead, we print a useful debug message to stderr and continue with the Cairo renderer. Signed-off-by: Emmanuele Bassi <ebassi@gnome.org>

GskTexture => GdkTexture We want this thing to replace GdkPixbuf, so it has to live in GDK.

GdkTexture * (* render_texture) (GskRenderer *renderer,
gsk: Add gsk_renderer_render_texture() ... and implement it for the Cairo renderer. It's an API that instructs a renderer to render to a texture. So far this is mostly meant to be used for testing, but I could imagine it being useful for rendering DND icons.

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.

void (* render) (GskRenderer *renderer,
gsk: Make GskRenderer.render() drawing context-agnostic We're going to need to allow rendering on a specific cairo_t in order to implement fallback code paths inside GTK; this means that there will be times when we have a transient GskRenderer instance that does not have a GdkDrawingContext to draw on. Instead of adding a new render() implementation for those cases and then decide which one to use, we can remove the drawing context argument from the virtual function itself, and allow using a NULL GdkDrawingContext when calling gsk_renderer_render(). A later commit will add a generic function to create a transient GskRenderer with a cairo_t attached to it. Renderers inside GSK will have to check whether we have access to a GdkDrawingContext, in which case we're going to use it; or if we have access to a cairo_t and a window.
