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.

Turn GskRenderNode into a derivable type Language bindings—especially ones based on introspection—cannot deal with custom type hiearchies.

Add get_type() functions for GskRenderNode subclasses The introspection scanner tries to match a type name with a get_type() function, in order to correctly identify a type as a class. If the function is not available, we have two choices: - add some special case inside the introspection scanner, similar to how GParamSpec subclasses are handled in GObject - add a simple get_type() function The latter is the simplest approach, and we don't need to change that much, since we still register all render nodes at once.

gsk: Add bounds member to RenderNode Instead of constantly recalculating this (especially recursively for parents!) we do it only on construction, because everything is immutable anyway. Also, most nodes had a bounds already and can use the new parent member instead. We also do direct access to the node bounds rather than calling gsk_render_node_get_bounds in various places, which means we do less copying.

gsk: Add high depth rendernode api Add private api to find out if the content of a render node should be considered 'deep'. The information is collected at creation time, so there is no tree-walking involved when we are using this information in the renderer. Currently, this comes down to whether there are any texture nodes with high depth textures in the subtree. In the future, we may want to allow marking gradient nodes in this way as well.
