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.

Use a single compilation symbol We use a compilation symbol in our build to allow the inclusion of specific headers while building GTK, to avoid the need to include only the global header. Each namespace has its own compilation symbol because we used to have different libraries, and strict symbol visibility between libraries; now that we have a single library, and we can use private symbols across namespaces while building GTK, we should have a single compilation symbol, and simplify the build rules.

gsk: Add GskPath This commit adds the basic infrastructure for paths. The public APIs consists of GskPath, GskPathPoint and GskPathBuilder. GskPath is a data structure for paths that consists of contours, which in turn might contain Bézier curves. The Bezier data structure is inspired by Skia, with separate arrays for points and operations. One advantage of this arrangement is that start and end points are shared between adjacent curves. A GskPathPoint represents a point on a path, which can be queried for various properties. GskPathBuilder is an auxiliary builder object for paths.

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.

rendernode: Put typedef into gsktypes.h Makes includes simpler for headers that want to use GskRenderNode.
