With this, all tables from the spec appendixes are in CFF.cpp.
This fixes a crash reading page 2 (and onward) of
2ThestructureoftheCIE1997ColourAppearanceModelCIECAM97s.pdf in
the pdffiles repo.
The encoding offset defaults to 0, i.e. the Standard Encoding.
That means reading the encoding only if the tag is present causes
us to not read it if a font uses the Standard Encoding.
Now, we always read an encoding, even if it's the (implicit) default
one.
The main encoding data maps glyph ID ("GID") to its codepoint.
If a glyph has several codepoints, then a secondary table mapping
codepoint to string ID ("SID") of the glyph's name is present.
(A separate table associates each glyph with its name already.)
I haven't seen this used in the wild, but the structure of the
supplemental data is also going to be needed for built-in encodings.
Prior to this commit, constructing a DS from a null DFS would cause a
nullptr deref, which broke (at least) Profiler.
This commit converts the null DFS to an empty DS, avoiding the nullptr
deref (until DFS loses its null state, or we decide to not make it
convertible to a DS).
After d2c7e1ea7d, there is now only one
user of LibPublicSuffix - the URL sanitation utility within LibWebView.
Rather than having an entire library for the small Public Suffix data
accessor, merge it into LibWebView.
Previously, all input elements were given a textbox-like style by
default, this was then undone by another CSS rule in the case of certain
types of input element. This commit makes it so that the first rule
simply ignores those types instead.

If the user runs /usr/lib/Loader.so and pass a second string to argv, we
will try to run it as if it was running that program without invoking
the dynamic loader explicitly.
According to the issue https://github.com/curl/curl/issues/12093 the
curl build doesn't properly detect that Serenity has getaddrinfo() and
outputs the following:
---
Performing Test HAVE_H_ERRNO_ASSIGNABLE
CMake Error: try_run() invoked in cross-compiling mode, please set the
following cache variables appropriately:
HAVE_H_ERRNO_ASSIGNABLE_EXITCODE (advanced)
---
Setting the CMake cache variable HAVE_GETADDRINFO_THREADSAFE=1 solves
the mentioned error.

Two bugs:
1. We decoded a u32, not an i32 as the spec wants
2. (minor) Our fixed-point divisor was off by one
Fixes text rendering in Bakke2010a.pdf in pdffiles, and rendering of
other fonts with negative width adjustments from optcode 255.
That PDF was produced by "Apple pstopdf" and uses font SFBX1200,
which is apparently a variant of Computer Modern. So maybe this
helps with lots of PDFs produced from TeX files, but I haven't
checked that.
A bit old but a relatively uncomplicated device capable of outputting
1920x1080 video with 32-bit color. Tested with a Voodoo 3 3000 16MB
PCI card. Resolution switching from DisplaySettings also works.
If the requested mode contains timing information, it is used directly.
Otherwise, display timing values are selected from the EDID. First the
detailed timings are checked, and then standard and established
timings for which there is a matching DMT mode. The driver does not
(yet) read the actual EDID, so the generic EDID in DisplayConnector now
includes a set of common display modes to make this work.
The driver should also be compatible with the Voodoo Banshee, 4 and 5
but I don't have these cards to test this with. The PCI IDs of these
cards are included as a commented line in case someone wants to give it
a try.
a396bb0 removed the palette field but did not update the allocation size
in `Bitmap::serialize_to_byte_buffer()`. This led to a few crashes (I
noticed this from a drag/drop crash in the file manager).
Fixes#21434
Previously, the null state of m_root_path was use to (subtly) mark the
parent of the root. The empty path is always replaced with "." so after
aeee98b there was no "parent of root" node. This lead to the file
manager crashing when opened.
I haven't seen this being used in the wild (yet), but it's easy
to implement, and with this we support all charset formats.
So we can now mention if we see a format we don't know about.
On my machine, benchmarking 3DFileViewer revealed ~2.5% of CPU time
spent in `Vector<GPU::Vertex>::try_append`. By carefully managing list
capacities, we can remove this method from profiles altogether.
Optimize a very hot function by always performing unchecked appends.
When benchmarking 3DFileViewer on my machine, this takes the time spent
in `gl_vertex` down from ~8% to ~2%.
LibSoftGPU used to calculate the normal transformation based on the
model view transformation for every primitive, because that's when we
sent over the matrix. By making LibGL a bit smarter and only update the
matrices when they could have changed, we only need to calculate the
normal transformation once on every matrix update.
When viewing `Tuba.obj` in 3DFileViewer, this brings the percentage of
time spent in `FloatMatrix4x4::inverse()` down from 15% to 0%. :^)
We were confusing the time spent rendering with the time spent rendering
_and_ waiting for the next frame, which is important since we render
frames on a timer.
Moving the DeviceManagement initialization, which is only needed by
userland in the first place, to after interrupt and time management
initialization (like other things that require randomness) allows the
SipHash initialization to access good randomness without problems.
Note: There currently is another, unrelated boot problem on aarch64,
which is not caused by SipHash as far as we know. This commit therefore
only fixes the SipHash regression.
From "10 String INDEX":
"Further space saving is obtained by allocating commonly occurring
strings to predefined SIDs. These strings, known as the standard
strings, describe all the names used in the ISOAdobe and Expert
character sets along with a few other strings common to Type 1 fonts. A
complete list of standard strings is given in Appendix A. The client
program will contain an array of standard strings with nStoStrings
elements. Thus, the standard strings take SIDs in the range 0 to
(nStaStrings-1)."
And "13 Charsets" says that charsets store SIDs.
Fixes all
"Couldn't find string for SID $n, going with space"
messages when going through the encoding pages (page 1010 and
thereabouts) in the PDF 1.7 spec.
Only really useful for reading SIDs in the Top DICT (copyright
text etc), which we currently don't do.
I haven't seen a difference from looking things up in the string
table. The only real effect from the commit that I need is that
it pulls a local resolve() labmda into a real function
resolve_sid(), which I want to call in a future commit.
But it makes things more spec-compliant, and if we ever want to
read SIDs in metadata in the future, now we can.
CobyCat has very kindly remastered their card backs to fit the new card
back dimensions of 72 x 102px with 3px rounded corners. This gives
cards 3px of inner border which looks much neater.
Also, all card names have been capitalized and the suffix '-deck'
removed to improve their appearance in GamesSettings.

The UnicodeData header cannot be included by any file other than .cpp
files within LibUnicode itself. Outside users cannot assume the header
will exist, as it will not be generated if the CMake option to do so is
disabled (ENABLE_UNICODE_DATABASE_DOWNLOAD).
We now produce a `matrix3d()` value when appropriate.
Some sites (such as gsap.com) request the resolved style for `transform`
when there's no viewport paintable, but the element itself does already
have a stacking context. This fixes crashes in that case, because we now
do not access the stacking context at all.
We also do not wrap the result as a StyleValueList any more. The
returned StyleValue is only serialized and exposed to JS, so making it a
StyleValueList has no effect.
As noted, there are two situations where an element will have no layout
node here:
1. The element is invisible in a way that it generates no layout node.
2. We haven't built the layout yet.
This protects against the second case, which would otherwise incorrectly
send us down the path of looking directly at the computed style.
