* Remove old rendering backend.Glenn Watson2016-10-181-779/+0
| | | | | | | | | | | | | | This removes paint threads, rust-layers dependency, and changes optional webrender types to be required. The use_webrender option has been removed, however I've left the "-w" command line option in place so that wpt runner can continue to pass that. Once it's removed from there we can also remove the -w option. Once this stage is complete, it should be fine to change the display list building code to generate webrender display lists directly and avoid the conversion step.
* Integrate stacking contexts into the display listMartin Robinson2016-10-131-49/+29
| | | | | | | | | | | | | | Integrate stacking contexts into the display list by adding two new entry types, PushStackingContext and PopStackingContext. This allows us to eliminate the ugly offsets map that DisplayList used to contain and seems to speed up display list construction. With this approach we are able to also completely prune pseudo-stacking contexts from the final display list and remove their (minimal) overhead from display list traversal Traversing the display list is also a bit simpler now. Additionally, this will allow easier editing of the DisplayList to properly support scrolling roots. The push/pop entries can be duplicated to clone complex StackingContext trees between layers.

Additionally it changes the behavior of the dirty flag to be propagated top down, to prevent extra overhead when an element is dirtied. This commit doesn't aim to change the behavior on Servo just yet, since Servo does extra job when dirtying the node related with DOM revision counters that might be necessary. CC @asajeffrey for the DOM revision counters stuff. When a node is dirty, do all its descendants really need to increment the revision counter, or is this an unintended effect? My intuition is that this is hurting performance quite a lot for servo. r? @bholley <!-- Please describe your changes on the following line: --> --- <!-- Thank you for contributing to Servo!

* | | Accumulate subpixels through stacking contextsMartin Robinson2016-07-271-0/+1
|/ / | | | | | | | | | | | | | | | | | | | | | | Instead of simply rounding layer origins and discarding subpixel offsets, accumulate them by transforming them into the space of the next child stacking context. This is an attempt to eliminate subpixel differences that are caused by different stacking context boundaries in reference tests. Currently these accumulated subpixels are only used for text positioning, but the plan is that they can be used for all drawing in the future.

* script: Keep the DOM-side viewport up to date when scrolling happens inPatrick Walton2016-05-311-1/+2
| | | | | | | | | | | | | | | WebRender. This happens asynchronously, just as it does in non-WebRender mode. This functionality is a prerequisite for doing proper display-list-based hit testing in WebRender, since it moves the scroll offsets into Servo (and, specifically, into the script thread, enabling iframe event forwarding) instead of keeping them private to WebRender. Requires servo/webrender_traits#55 and servo/webrender#277. Partially addresses #11108.

* Flatten display list structureMartin Robinson2016-03-011-249/+319
| | | | | | | | | | | | | | | | | | | | | | | Instead of producing a tree of stacking contexts, display list generation now produces a flat list of display items and a tree of stacking contexts. This will eventually allow display list construction to produce and modify WebRender vertex buffers directly, removing the overhead of display list conversion. This change also moves layerization of the display list to the paint thread, since it isn't currently useful for WebRender. To accomplish this, display list generation now takes three passes of the flow tree: 1. Calculation of absolute positions. 2. Collection of a tree of stacking contexts. 3. Creation of a list of display items. After collection of display items, they are sorted based upon the index of their parent stacking contexts and their position in CSS 2.1 Appendeix E stacking order. This is a big change, but it actually simplifies display list generation.
