The set_main_widget<T>() function only calls the construct and not
`try_create()` that the GMLCompiler generates so all calls to
`find_descendant_of_type_named()` would result in null
pointers that would resolve in a crash.
Implements following rule from CSS Overflow Module Level 3:
"The visible/clip values of overflow compute to auto/hidden
(respectively) if one of overflow-x or overflow-y is neither visible
nor clip."
On argument swapping to put positional ones toward the end,
m_arg_index was pointing at "last arg index" + "skipped args" +
"consumed args" and thus was pointing ahead of the skipped ones.
m_arg_index now points after the current parsed option arguments.
Previously, on systems where pressing Enter would generate "\r\n", only
the '\r' character was being sent to the event handler. This change
ensures consistent behavior across platforms regardless of their native
line ending characters.
When WebDriver asks to destroy a window, we can hit this case with no
active browsing context. This seems odd, but perhaps is a spec issue as
well. Just log to dbgln for now.
This aligns it better with the current state of the spec.
There's still some functions and data members that need moved into
Navigable or TraversableNavigable, but we can leave those for the next
cleanup PR.
This check has been if (false && stuff) for quite a while, since the
transition to Navigables. No one updates the BrowsingContext's session
history, so the check for it having an about blank document and only an
about blank document is always false.
IncludeCleaner is a new feature of clang-tidy/clangd that adds upstream
support for the include-what-you-use (IWYU) tool's checks.
However, this tool is very noisy on our codebase. It can be enabled by
individual contributors at their leisure.
Previously, if we wanted to to e.g. do linear interpolation in 2-D,
we'd get a sample point like (1.3, 4.4), then get 4 samples around
it at (1, 4), (2, 4), (1, 5), (2, 5), then reduce the 4 samples
to 2 samples by computing the combined samples
`0.3 * f(1, 4) + 0.7 * f(2, 4)` and `0.3 * f(1, 5) + 0.8 * f(2, 5)`,
and then 1-D linearly blending between these two samples with the
factor 0.4. In the end we'd multiply the first value by 0.3 * 0.4,
the second by 0.7 * 0.4, the third by 0.3 * 0.6, and the third by
0.7 * 0.6, and then sum them all up.
This requires computing and storing 2**N samples, followed by
another 2**N iterations to combine the 2**N sampls to a single value.
(N is in practice either 4 or 3, so 2**N isn't super huge.)
Instead, for every sample we can directly compute the product of
weights and sum them up directly. This lets us omit the second loop
and storing 2**N values, in exchange for doing an additional O(n)
work to compute the product.

form 3.42s to 3.08s on my machine, almost 10% faster (and less code).
Here cmyk.jpg is a 2253x3080 cmyk jpeg, and USWebCoatedSWOP.icc is an
mft2 profile with input tables with 256 samples and a 9x9x9x9 CLUT.
The LibPDF change is covered by TEST_CASE(sampled) in LibPDF.cpp,
and the LibGfx change is basically the same change as the one in
LibPDF (where the test results don't change) and the output
subjectively looks identical. So hopefully this causes indeed no
behavior change :^)
This is useful for working with CMYK jpegs extracted from PDFs
by mutool. CMYK channels for jpegs in PDFs are inverted compared to
CMYK channels in standalone jpegs (!), and mutool doesn't compensate
for that.
You can now do:
mutool extract ~/Downloads/0000/0000711.pdf 461
Followed by:
Build/lagom/bin/image -o out.png \
--invert-cmyk \
--assign-color-profile \
Build/lagom/Root/res/icc/Adobe/CMYK/USWebCoatedSWOP.icc \
--convert-to-color-profile serenity-sRGB.icc \
cmyk.jpg
Doesn't exactly roll off the keyboard, but at least it's possible.
(We should probably add an implicit default CMYK color profile if
the input file doesn't have one, and assume conversion to sRGB when
saving to a format that can only store RGB.)
The IPC layer between chromes and LibWeb now understands that multiple
top level traversables can live in each WebContent process.
This largely mechanical change adds a billion page_id/page_index
arguments to make sure that pages that end up opening new WebViews
through mechanisms like window.open() still work properly with those
extra windows.
