- Use umask() to prevent the parent process from tampering with the mode
bits of replacement passwd and shadow files.
- Use fchmod() to set new shadow files to mode 0600.
We should not expect LibC functions to clear `errno` on success,
so if we want to use it for error checking after a call, we need
to clear it before the call.
This means you can now do queries like:
```css
@media (400px <= width < 800px) { }
```
Chromium and Firefox which I tested with both don't support this yet, so
that's cool. :^)
Past me decided that the grammar was overly verbose and I could do it
better myself. Which seemed fine until the spec changed and I didn't
know how to integrate the changes. Lesson learned! :^)
Rather than have a function for every single part of the grammar, I have
written some as lambdas, and combned `<media-condition>` and
`<media-condition-without-or>` into one function. But otherwise it's
close to the spec, with comments listing the part of the grammar being
parsed, so hopefully it will be easier to make future adjustments!
This does not add any new functionality.
Web::CSS::MediaQuery::MediaFeature::Type was getting a bit ridiculous!
Also, this moves the detection of "min-" and "max-" media-features into
the MediaFeature itself, since this is an implementation detail, not
part of the spec.
Having these in here was a hack to support the other hack of making
media-queries use StyleValues. Now they don't do that, so we can remove
these again and keep things hygienic.
Previously, we were using StyleValues for this, which was a bit of a
hack and was brittle, breaking when I modified how custom properties
were parsed. This is better and also lets us limit the kinds of value
that can be used here, to match the spec.
If we didn't define our own `move` and `forward` and inject it into the
`std` namespace, then we would error just after trying to `using` those,
if no one has included it before. Now, we will include `utility` from
the STD if we aren't replacing the `std`.
Without this change, floor(-0.125) returned 0.
This is because the number has a fraction part even if mantissa is zero
while the unbiased exponent is negative.
The names of some variables were also made clearer.

This was currently crashing Half-Life because it was a considered an
"Unknown" specifier. We can use the same case statement as the regular
hex format conversion (lower case 'x'), as the backend
to convert the number already supports upper/lower case input, hence
we get it for free :^)
We need to use the volatile keyword when mapping the device registers,
or the compiler may optimize access, which lead to this QEMU error:
pci_nvme_ub_mmiord_toosmall in nvme_mmio_read: MMIO read smaller than
32-bits, offset=0x0
This displays statistics regarding frame timings and number of pixels
rendered.
Timings are based on the time between draw_debug_overlay() invocations.
This measures actual number of frames presented to the user vs. wall
clock time so this also includes everything the app might do besides
rendering.
Triangles are counted after clipping. This number might actually be
higher than the number of triangles coming from LibGL.
Pixels are counted after the initial scissor and coverage test. Pixels
rejected here are not counted. Shaded pixels is the percentage of all
pixels that made it to the shading stage. Blended pixels is the
percentage of shaded pixels that were alpha blended to the color buffer.
Overdraw measures how many pixels were shaded vs. how many pixels the
render target has. e.g. a 640x480 render target has 307200 pixels. If
exactly that many pixels are shaded the overdraw number will read 0%.
614400 shaded pixels will read as an overdraw of 100%.
Sampler calls is simply the number of times sampler.sample_2d() was
called.
This modifies sys$chown to allow specifying whether or not to follow
symlinks and in which directory.
This was then used to implement lchown and fchownat in LibC and LibCore.
