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.

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.

Add GskGLShaderNode and GskGLShader A GskGLShader is an abstraction of a GLSL fragment shader that can produce pixel values given inputs: * N (currently max 4) textures * Current arguments for the shader uniform Uniform types are: float,(u)int,bool,vec234) There is also a builder for the uniform arguments which are passed around as immutable GBytes in the built form. A GskGLShaderNode is a render node that renders a GskGLShader inside a specified rectangular bounds. It renders its child nodes as textures and passes those as texture arguments to the shader. You also pass it a uniform arguments object.

Turn GskRenderNode into a derivable type Language bindings—especially ones based on introspection—cannot deal with custom type hiearchies. Luckily for us, GType has a derivable type with low overhead: GTypeInstance. By turning GskRenderNode into a GTypeInstance, and creating derived types for each class of node, we can provide an introspectable API to our non-C API consumers, with no functional change to the C API itself.

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.

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).

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.

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.

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.

Add GskGLShaderNode and GskGLShader A GskGLShader is an abstraction of a GLSL fragment shader that can produce pixel values given inputs: * N (currently max 4) textures * Current arguments for the shader uniform Uniform types are: float,(u)int,bool,vec234) There is also a builder for the uniform arguments which are passed around as immutable GBytes in the built form. A GskGLShaderNode is a render node that renders a GskGLShader inside a specified rectangular bounds. It renders its child nodes as textures and passes those as texture arguments to the shader. You also pass it a uniform arguments object.

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.
