This needs to happen before prototype/constructor intitialization can be
made lazy. Otherwise, GC could run during the C++ constructor and try to
collect the object currently being created.
Currently, for each exposed interface, we generate one massive function
to create every Web constructor and prototype. In an effort to lazily
create these instead, this first step is to extract the creation of each
of these into its own method.
First, this generates a forwarding header for all IDL types. This is to
allow callers to remain unchanged without forcing them to include the
(very heavy) generated IDL headers. This header is included by LibWeb's
forwarding header.
Next, this defines a base template method on Web::Bindings::Intrinsics
to create a prototype/constructor pair. Specializations of this template
are now generated in a new .cpp file, IntrinsicDefinitions.cpp. The base
Intrinsics class is updated to use this new method, and will continue to
cache the result.
Last, some WebAssembly classes are updated to use this new mechanism.
They were using some ad hoc cache keys that are now in line with the
generated specializations.
That one massive function is still used to invoke these specializations,
so they are not lazy as of this commit.
Also add some tests that ensure that the input and output streams match
each other, because I can't wrap my head around what the internal
representation looks like.
This moves the CSS gradient painting to the painter creating:
- Painter::fill_rect_with_linear_gradient()
- Painter::fill_rect_with_conic_gradient()
- Painter::fill_rect_with_radial_gradient()
This has a few benefits:
- The gradients can now easily respect the painter scale
- The Painter::fill_pixels() escape hatch can be removed
- We can remove the old fixed color stop gradient code
- The old functions are now just a shim
- Anywhere can now easily use this gradient painting code!
This only leaves the color stop resolution in LibWeb (which is fine).
Just means in LibGfx you have to actually specify color stop positions.
(Also while here add a small optimization to avoid generating
excessively long gradient lines)
This change fixes problem that y position of blocks with
clearance might not include border_top and padding_top
by changing `place_block_level_element_in_normal_flow_vertically`
to accept y position without `border_box_top` and adding it
on the last step when clearance is already taken in account.

Resolves issue where a panic would occur if the file system failed to
initialize or mount, due to how the FileSystem was already added to
VFS's list. The newly-created FileSystem destructor would fail as a
result of the object still remaining in the IntrusiveList.
Since AK can't refer to LibUnicode directly, the strategy here is that
if you need case transformations, you can link LibUnicode and receive
them. If you try to use either of these methods without linking it, then
you'll of course get a linker error (note we don't do any fallbacks to
e.g. ASCII case transformations). If you don't need these methods, you
don't have to link LibUnicode.
DeprecatedFlyString relies heavily on DeprecatedString's StringImpl, so
let's rename it to A) match the name of DeprecatedString, B) write a new
FlyString class that is tied to String.
Previously, we would assume that all standard 14 fonts use a
TrueTypeFont dictionary. Now we render them in Type1Font as well,
given that it doesn't contain a PostScript font program.
While this subtable ID is supposed to be deprecated, it is used heavily
in PDF files.
It supports mapping one or two-byte values, with quite a large list of
encodings to tell you which one to expect.
For our use case, we ignore this encoding ID and just pick the first
subtable with this platform ID. Unsupported encodings will get caught
by Subtable::glyph_id_for_code_point() anyway.
The ports `libvorbis`, `readline` and `timidity` would not install on
macOS as a result of using `sed -i` without an extension provided. GNU
sed is available through Homebrew, but it does not replace `sed` by
default.
Instead, provide a new `sed_in_place` function that calls `sed` with the
right arguments.
This patch replaces the bespoke rendering engine in Presenter with a
simple pipeline that turns presentations into single-page HTML files.
The HTML is then loaded into an OutOfProcessWebView.
This achieves a number of things, most importantly:
- Access to all the CSS features supported by LibWeb
- Sandboxed, multi-process rendering
The code could be simplified a lot further, but I wanted to get the new
architecture in place without changing anything about the file format.
By setting this hint, you indicate to OOPWV that the content inside will
scale itself to the viewport size. In such situations, it's fine for
OOPWV to reuse a scaled version of an outdated backing store while the
view is being resized.
Clicking analyze or deleting a file would always cause the tree view in
the widget to reset back to viewing the root. This was changed to stay
in the directory currently being viewed
