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.

* GskRenderNodeType:
* @GSK_NOT_A_RENDER_NODE: Error type. No node will ever have this type.
* @GSK_CONTAINER_NODE: A node containing a stack of children
* @GSK_CAIRO_NODE: A node drawing a #cairo_surface_t
gsk: Add gsk_color_node_new()
2016-12-13 02:35:56 +00:00

gsk: Add GskRenderNodeType For now, this is unused.
2016-12-10 20:42:01 +00:00
* @GSK_TEXTURE_NODE: A node drawing a #GskTexture
gsk: gsk_render_node_set_transform() => GskTransformNode Instead of having a setter for the transform, have a GskTransformNode. Most of the oprations that GTK does do not require a transform, so it doesn't make sense to have it as a primary attribute. Also, changing the transform requires updating the uniforms of the GL renderer, so we're happy if we can avoid that.
2016-12-12 23:11:06 +00:00
* @GSK_TRANSFORM_NODE: A node that renders its child after applying a
* matrix transform
gsk: Replace gsk_render_node_set_opacity() ... with gsk_opacity_node_new(). Also implement support for opacity in gtk_widget_snapshot() using this new node.
2016-12-13 04:49:57 +00:00
* @GSK_OPACITY_NODE: A node that changes the opacity of its child
gsk: Add gsk_clip_node_new() The node is a simple clipping node: It does a rectangular clip of its contents.
2016-12-13 08:37:51 +00:00
* @GSK_CLIP_NODE: A node that clips its child to a rectangular area
gsk: Add GskRoundedRect It's essentially a port of GtkRoundedBox to graphene.
2016-12-13 18:02:12 +00:00
* @GSK_ROUNDED_CLIP_NODE: A node that clips its child to a rounded rectangle
gsk: Add blend nodes Implement blend mode support in GTK background compositing with it.
2016-12-15 03:24:37 +00:00
* @GSK_BLEND_NODE: A node the blends two children together
gsk: Add GskRenderNodeType For now, this is unused.
2016-12-10 20:42:01 +00:00
*
* The type of a node determines what the node is rendering.
