Some icons only exist in 16x16 and we should still allow them to be
loaded via the LibGUI default icon system.
This patch also reimplements GUI::default_icon() as a MUST() wrapper
around try_create_default_icon().
The document describes the implications of enabling and disabling that
option on the ability to enable SMP mode, and describes the requirements
for enabling IOAPIC mode even without enabling SMP mode.
This fixes the problem before, where searching "Shell" would list
"Shell-vars" in the results, but searching "Shell-vars" would make it
disappear.
Also removed some now-unnecessary includes.
I found it strange that `man` and `Help` did not accept the same command
line arguments since they are so similar. So... now they do. :^)
This means you can now open for example the `tar` man page in Help with
`Help tar`, or `Help 1 tar` if you want to disambiguate between pages in
different sections.
If the result is not found, it falls back to the previous behavior,
treating the input as a search query.
Initially I had this written as two optional positional arguments, but
when told to parse `[optional int] [optional string]`, and then given a
string input, ArgsParser forwards it to the [optional int], which then
fails to parse. Ideally it would pass it to the second, [optional
string] arg instead, but that looks like a fairly big change to make to
ArgsParser's internals, and risk breaking things. Maybe this ugly hack
will be an incentive to fix it. :^)
Previously, launching Help with a query like `Help tar` left the page
blank, which looks like something has gone wrong. Instead, let's show
the usual welcome page.
This patch adds a 512 frame timeline to Magnifier and the ability to
step through it with the arrow keys.
This makes it easier to check Serenity animations frame by frame for
correctness etc.
Before, `SoftwareRasterizer` was iterating over all 32 possible texture
units for each fragment and checking each if they're bound to a texture.
After this change, an intrusive list containing only texture units with
bound textures is passed to the rasterizer. In GLQuake, this results in
a performance improvement of ~30% (from 12 to 16 FPS in the first demo)
on my machine.
This smaller block size allows us to use an `u8` for the pixel mask
during triangle rasterization. These changes result in better FPS in
3DFileViewer, which periodically shoots up to 250-300 FPS on my
machine. Before, the peaks were somewhere in the range of 160-170 FPS.
For setreuid and setresuid syscalls, -1 means to set the current
uid/euid/gid/egid value, to be more convenient for programming.
However, for other syscalls where we pass only one argument, there's no
justification to specify -1.
This behavior is identical to how Linux handles the value -1, and is
influenced by the fact that the manual pages for the group of one
argument syscalls that handle ID operations is ambiguous about this
topic.
Previously we multiplied the interpolated texture coordinates by
width - 1 and height - 1 instead of width and height which resulted in
some wrongly mapped textures, especially visible in the glquake light
maps.
This also corrects the wrap mode being wrongly swapped for s/t
coordinates.
Since we do not have texture borders implemented yet we always use
GL_CLAMP_TO_EDGE for all clamping wrap modes for the time being.
