Moves DirectoryServices out of LibCore (because we need to link with
LibIPC), renames it Desktop::Launcher (because Desktop::DesktopServices
doesn't scan right) and ports it to use the LaunchServer which is now
responsible for starting programs for a file.
Step one of moving DesktopServices::open handling out of process. This
makes it easier to do things like read in associations for which program
opens which files or protocols. This gives users the ability to modify
the associations without having to rebuild :^)
Various optimisations to speed up LZWDecoder
- Take advantage of the fact that we add new codes in the order they are
discovered so no need to store the code as part of a separate
CodeTableEntry structure. Instead we store directly store vectors of
colors and the code is the index into the vector.
- Cache current table capacity to avoid calling pow2 every time.
- Prevent some unnecessary vector copies by returning by reference from
get_output.
Adds methods to determine whether an image is animated, how many times
the animation loops, the number of frames, and to get individual frames.
Implements stubs of these methods for PNGImageDecoderPlugin and
GIFImageDecoderPlugin.
This is a workaround for the silly issue where some content would move
one pixel upward on every layout. The block layout code was finding
the list item marker and doing regular inline layout on it. We were not
prepared to handle this, which caused it to move in a silly way.
For now, just regenerate markers on every layout to work around the
issue. In the future we should figure out a nice way to layout markers.
It didn't feel right to have a "DHCPClient" in a "Servers" directory.
Rename this to Services to better reflect the type of programs we'll
be putting in there.
Ultimately we should not panic just because we can't fully commit a VM
region (by populating it with physical pages.)
This patch handles some of the situations where commit() can fail.
The existing scanline method works just fine, and only needs the points
to be available as floats.
This commit reverts the complex polygon mitigation, and instead fixes
the rasterization process to avoid generating complex polygons because
of precision issues.
This allows the painter to render filled complex shapes better, by
constructing a path graph for (interesting) intersecting lines and
omitting lines from the containing segments if they are detected
to take no part in defining the edges of a shape.
This approach would still fail if there are multiple logical shapes
that are confined to the collection of lines.
For instance, two polygons intersecting each other in a way that one
vertex of polygon A ends up inside polygon B.
we would detect that polygon A's edges are part of the shape
(technically correct) even though they are not a part of polygon B at
all.
The ECMAScript spec defines multiple equality operations which are used
all over the spec; this patch introduces them. Of course, the two
primary equality operations are AbtractEquals ('==') and StrictEquals
('==='), which have been renamed to 'abstract_eq' and 'strict_eq' in
this patch.
In support of the two operations mentioned above, the following have
also been added: SameValue, SameValueZero, and SameValueNonNumeric.
These are important to have, because they are used elsewhere in the spec
aside from the two primary equality comparisons.
