Skipping all stacking contexts with a size larger than 10000px in one
dimension was a mistake because it also affects pages that are simply
tall due to having a lot of content. Instead, we only need to skip if
the stacking context requires the allocation of a framebuffer that
could possibly fail.

By caching the layout node and its computed values in locals, we can
avoid the small amount of redundant work needed to look them up every
single time.
This removes indirection when asking if a paintable is positioned,
floating, etc.
Removes a bunch of 1-1.5% items in the profile when hovering links
on ziglang.org.
Update to the latest version of the spec which was refactored to use
time zone methods record. This requires updating a whole bunch of
callers to pass through a record too.
This also ends up improving exceptions on a missing
getOffsetNanosecondsFor method.
This can be perfectly valid, and depends on the property being animated.
For example, interpolating between the StyleValue "none" (an identifier)
and a TransformationStyleValue is perfectly defined.
In the upcoming commits where we properly handle transformation
interpolation, it actually becomes easier to change this back to custom,
so lets do that since its more correct anyways.
Introduces CIDIterator, an iterator type for iterating over CIDs.
Also introduces Type0CMap which can return a CIDIterator given some
bytes.
The existing code of treating the bytes as an identity map of
big-endian u16s is now implemented in IdentityType0CMap.
No behavior change.
We currently use 0.6GB for a clean build with sanitizers enabled. This
will allow us to have ~3 clean builds cached and save 3GB of disk space
on CI. (The effect is actually double, because Azure archives the cache
in a tar file before uploading).
Since commit e6df1c9988 which switched us
over to using the syscall/sysret instruction the second syscall
argument changed from rcx to rdi. Update strace as well to print the
actually correct values for the second arg.
...to avoid allocating a copy of glyph run for painting commands. We
can't simply save pointers to a glyph run in layout/paintable tree
because it should be safe to deallocate layout and paintable trees
after painting commands are recorded, if in the future we decide to
move command execution to a separate thread.
Instead of allocating a new glyph run to scale glyph positions and
fonts, a scale factor could be encoded in a paint command and applied
later during command execution.
Instead of allocating a new glyph run solely to shift each glyph by the
painter's offset, this offset could be encoded in a paint command and
applied later during command execution.
Every single client of this function was immediately calling paintable()
on the result anyway, so there was no need to return a layout node!
This automatically leverages the cached containing block pointer we
already have in Paintable, which melts away a bunch of unnecessary
traversal in hit testing and painting. :^)
