Everytime a new LayoutContext was created, it created a new origin which
caused endless stream of image loads to occur in case of reflow. The reason
for this was that the existing image, although cached successfully, was not
used because the entry in hashmap did not match because of different(new)
origin.
This is solved by storing the origin of a window in enum ScriptReflow and
used in creating new LayoutContext in case of reflow.
This query is used to get the clientTop, clientWidth, clientHeight,
clientLeft properties of DOM objects. "NodeGeometry" doesn't really
capture what these properties do as they often are returning the width
of element border.
There are a few canvas2d-related dependencies that haven't updated, but they
only use euclid internally so that's not blocking landing the rest of the
changes.
Given the size of this patch, I think it's useful to get this landed as-is.
Instead of per-document. This also allows to reuse this thread-pool if needed
for other stuff, like parallel CSS parsing (#22478), and to share more code with
Gecko, which is always nice.
This allows servo to use the ExternalScrollId API from WebRender fixing
some issues related to duplicate scroll root ids.
Fixes#17176.
Fixes#19287.
Fixes#19648.
This enables us to implement Element::has_css_layout_box() in a more
direct way, and also enables us to remove some of the existing more
specific queries.
Fixes#19811.
This is the second half of switching over to WebRender for hit testing.
Now that WebRender gives us the location of the hit tested point in the
display item, we can use that to calculate text index.
This trades quite a bit of complicated code in Servo for few more
messages and a significant performance improvement. In particular,
WebRender can search the entire display list at once instead of
ping-ponging down the pipeline tree. This allows us to send mouse
events to the correct pipeline immediately.
This is a patch that unifies a bit how Gecko and Stylo stylesheets work, in
order to be able to eventually move the stylesheets into the stylist, and be
able to incrementally update the invalidation map.
The alias is left there temporarilly and will be removed completely in a later commit where
also components/style/gecko/generated/structs_{debug|release}.rs are re-generated (they still
use the old alias).
Scroll roots are no longer nested containers holding items, so instead
we need to track the offsets of each, carefully handling fixed position
items and stacking contexts that create new reference frames.
Additionally, we remove the complexity of the pre-computed page scroll
offset, instead opting to send script scrolls to the layout task in
order to more quickly have a ScrollState there that matches the
script's idea of the scroll world.
Fixes#16405.
This avoids the need for multiple layout RPC operations immediately
following return of control to script. This means that layout and
script can continue to operate in parallel at this point, rather
than one potentially waiting on the shared mutex to be unlocked.
