Unbreaks Windows build. resolve_integer returns an i64 making creation
of a StepsEasingFunction with its result a narrowing conversion before
this change as a long is 32 bits on Windows.
Steps 4 and 5 were swapped since marking all the nodes between the start
and end of the selection now also marks the end node as full, even if it
should be marked as End.
There could be extra logic to avoid marking it if it is a text node, but
this seems easier.
As a whole, this fixes partially selected non-text nodes. In such cases,
where the selection starts or ends inside a node with descendants, it is
impossible to just select from the start node to the end node since that
would select all descendants of the start node and none of the end node.
Previously, this was only half considered and only if the start node was
a descendant of the end node.
After we bind the surface to the context for the first time when
allocating the backing image, it internally has a permanent reference
count above 0.
If we switch to a different context and back, the switch back will fail
because the surface has a reference count, which makes ANGLE think
we're trying to use it on a different thread.
However, we can avoid this by using surfaceless contexts, since we
don't use the default framebuffer.
Fixes multiple WebGL contexts on the page freezing.
To consistently update the backing stores in reallocate_backing_stores()
the variables storing the backing stores need to be set to nullptr at
the start so that they are properly update later on near the end of the
function.
There are some non-math functions (such as tree counting functions)
which we should allow within `calc()`s . This commit implements the
initial infrastructure for this.
We don't yet parse any of these non-math functions in
`parse_a_calculation` so there is no functional change.
Adds support for `sibling-index()` and `sibling-count()` when parsing
`<number>` and `<integer>`. This is achieved by a new
`TreeCountingFunctionStyleValue` class which is converted within
`absolutized` to `NumberStyleValue` and `IntegerStyleValue` respectively
There are still a few kinks to work out in order to support these
everywhere, namely:
- There are some `StyleValue`s which aren't absolutized (i.e. those
which are stored within another `StyleValue` without an
`absolutize()` method.
- We don't have a way to represent this new `StyleValue` within
`{Number,Integer}OrCalculated`. This would be fixed if we were to
instead just use the `StyleValue` classes until style computation at
which time they would be absolutized into their respective
primitives (double, i64, etc) bypassing the need for *OrCalculated
entirely.
Tree counting functions should be resolved at style computation time -
to do this we will need to know the element's sibling count and index.
This commit computes that information and propagates it to the various
`StyleValue::to_computed_value` methods.
Some contexts (e.g. descriptors, media conditions) don't allow tree
counting functions, this commit adds an easy way to check if the current
value context is one of those.
This deduplicates a lot of sensitive pointer math by using Span, which
performs this math for us with more safety checks and with type
information.
This also allows us to use the correctly typed Span for typed arrays,
which automatically fixes srcOffset to now offset by the number of
elements instead of bytes. This goes for srcLengthOverride too.
Fixes the Rive animations on Shopify's homepage not appearing.
Fixes some Unity applications such as ArcViewer having missing
graphics.
Peek is used to determine if the current chunk is
the last and if so, add trailing box metrics.
For this to work correctly, it must be done only
after calling next(), otherwise peek gives us the
current chunk.
We no longer rely on parsing easing functions before keywords so this
can be moved down with the other parse_for_type calls.
`parse_for_type` is used for more than just parsing easing functions so
the variable name `maybe_easing_function` was misleading
This excludes `step-end` and `step-start` which are expected to be
converted to the equivalent function at parse time.
We are expected to serialize these as the explicit keywords - previously
we would parse as `EasingStyleValue` and serialize equivalent functions
as the keywords. This caused issues as we would incorrectly serialize
even explicit functions as the keyword.
This also allows us to move the magic easing functions to
`EasingFunction` rather than `EasingStyleValue` which is a bit tidier
Previously we were doing this ad-hoc later in the process but we now
have the `calc` clamping system which can simplify things.
This reveals some false-positives in that we don't handle relative
lengths within these `calc`s but these are fixed in the next commit
Before this change we would maintain explicit signs when serializing
e.g. `animation-iteration-count: calc(+1)` would serialize as `calc(+1)`
rather than `calc(1)` as intended
Canonicalization can require information that is only known after
compute time (i.e. resolved relative lengths within calcs).
This also allows us to get rid of the `had_explicit_input` flag and just
rely on whether Optional has a value
Otherwise the layout tree will still contain the top layer element(s).
Fixes Steam Events & Announcements `<dialog>` modal visually not fully
disappearing upon removal.
In some cases a document may lack an associated window - to fix this for
now we just return false but perhaps there are some media queries we
should still attempt to resolve.
