Makes the Audio applet, Taskbar clock, CommandPalette, EmojiPicker,
and Assistant work as Popup windows. Popups are frameless, unmovable,
and unresizable by default, in addition to their preemptive function.
Also sets Assistant not to obey widget min size so its search result
area resizes correctly
and the CaptureInput mode. They are a source of unneeded complexity
in WindowServer and have proven prone to regressions, so this patch
replaces them with a simple input preemption scheme using Popups.
Popup windows now have ergonomics similar to menus: When open,
a popup preempts all mouse and key events for the entire window
stack; however, they are fragile and will close after WindowServer
swallows the first event outside them. This is similar to how combo
box windows and popups work in the classic Windows DE and has the
added benefit of letting the user click anywhere to dismiss a popup
without having to worry about unwanted interactions with other
widgets.
with WindowInput{Preempted,Restored} Events and allow Widgets to save
the state of their focus preemption. As of now, only Popups will
preempt input and trigger these events.
For flate and lzw filters, the data can be transformed by this
predictor function to make it compress better. For us this means that
we have to undo this step in order to get the right result.
Although this feature is meant for images, I found at least a few
documents that use it all over the place, making this step very
important.
We previously compared two unrelated values to determine if we parsed
the xref table to completion. We now check if we added every subsection
instead, and double check to make sure we never read past the end.
This filter basically tells us that we are dealing with a JPEG.
Note that by serializing the resulting image we assume that this filter
is the last one in the chain, everything else would be highly unlikely.
We currently don't support ICC color spaces and fall back to a "simple"
one instead.
If no alternative is specified however, we are allowed to pick the
closest match based on the number of color components.
This fixes an issue where we would show an error message on every
subsequent paint event, making it impossible to close or use the
application further.
Some more architectural work is needed if we want to invalidate the
sidebar entries as well.
And TRY early during initialization in FontEditor to leave the app
in a valid state on error. Fixes OOM crashes when cloning the original
font for highlight modifications.
Like other apps, FontEditor now organizes widget visibility toggles
under a View->Layout submenu. The main toolbar and the status bar
can now be turned on and off.
Each GenericInterruptHandler now tracks the number of calls that each
CPU has serviced.
This takes care of a FIXME in the /sys/kernel/interrupts generator.
Also, the lsirq command line tool now displays per-CPU call counts.
These lambdas were marked mutable as they captured a Ptr wrapper
class by value, which then only returned const-qualified references
to the value they point from the previous const pointer operators.
Nothing is actually mutating in the lambdas state here, and now
that the Ptr operators don't add extra const qualifiers these
can be removed.
Even if the pointer value is const, the value they point to is not
necessarily const, so these functions should not add the qualifier.
This also removes the redundant non-const implementations of these
operators.

This also removes the redundant non-const implementations of these

These functions are now implemented in terms of getpwent_r() which
allows us to remove two FIXMEs about global variable shenanigans.
I'm also adding tests for both APIs. :^)
