The initial signs were wrong for the deltas of f(x), the ellipse
equation. This seemed to be fine for larger circles/ellipses but
broke things at a small scale, this was previously fixed with a
horrible "error = error / 4" hack. With this change, all ellipses
look a little better :^)
This also fixed a signed integer overflow Andreas found with UBSAN,
which happened for circles with a 1px radius.
This is an initial implementation of the accname standard. There is
still some of the algorithm left unimplemented that we will need
to implement in the future. However, as is, this implementation is
sufficient for basic pages.
Using the walk_device_tree helper, we can walk the device tree from the
beginning looking for a specific property node. It's still missing the
ability to get property lists, string lists, and property-specific data.
This subdirectory is meant to hold all constant data related to the
kernel. This means that this data is never meant to updated and is
relevant from system boot to system shutdown.
Move the inodes of "load_base", "cmdline" and "system_mode" to that
directory. All nodes under this new subdirectory are generated during
boot, and therefore don't require calling kmalloc each time we need to
read them. Locking is also not necessary, because these nodes and their
data are completely static once being generated.
With this, common v4 profiles, such as embedded into jpgs by iPhones
(when configured to write jpegs) or Pixel phones, are identical to
the input when reexported :^)
Restart markers are supposed to be applied every restart interval.
However, in these loops macroblocks are counted taking the luma sampling
factor into consideration. Meaning that we need to correct this factor
when testing if we should reset the DC.
Also, the decoder was discarding the first byte of every scan with a set
restart interval, as `0 % n == 0` is always true.
This commit allows the text tool's internal TextEditor component to
handle keyboard shortcuts that would normally be handled by menu
actions.
The shortcuts that can now be used are: cut, copy, paste, undo, redo
and select all.
Previously, we only saved the REPL history when the interpreter was
shutdown with a signal. This change ensures that we save the history
when a user uses `exit()`.
This creates a cached bitmap for each unique screen resolution, which
allows us to share it between displays with the same resolution. If
the resolution is the same as the wallpaper, we can just use the
wallpaper as-is.
When viewing a deeply nested path, there may be very little of the
PathBreadcrumbbar itself visible to double-click on. This solves that
by allowing double-clicks on its segment buttons to behave the same.
(With the caveat that it first selects the double-clicked segment.)
In order to make this work, `on_double_click` now takes the modifiers
instead of the MouseEvent. In this case we don't use it so that's fine,
but maybe we should make all mouse callbacks consistently take the
MouseEvent& as a parameter.
This Widget wraps both a Breadcrumbbar and a TextBox for editing the
path manually, based heavily on the existing code in FileManager.
Breadcrumbbar itself requires outside code to micro-manage what it does.
This class provides a simpler interface for it: Users don't have to
worry about segments, they just give/receive a string for the current
path.
I'm not sure why this isn't caught on other people's setups or CI, but
when building on NixOS it fails with:
error: comparison of integer expressions of different signedness:
‘size_t’ {aka ‘long unsigned int’} and ‘int’ [-Werror=sign-compare]
This is necessary to support the wayland protocol.
I also moved the CMSG_* macros to the kernel API since they are used in
both kernel and userspace.
this does not break ntpquery/SCM_TIMESTAMP.
With this, simple v4 matrix profiles using parametric curves, such as
Compact-ICC-Profiles/profiles/sRGB-v4.icc, can be completely serialized
and the serialized file can be read again by `icc` :^)
