This allows performing an action based on whether something
was actually added or removed without having to look it up
prior to calling set() or remove().
In order to calculate a thumb size that is a representation
of the visible portion (page) of the content, that information
needs to be taken into account.
If selecting in a large icon view, and dragging the mouse outside
of the widget, or close to the border of it, start scrolling
automatically. This allows for selecting large amount of items
that exceed the amount that can be displayed.
This Emulator sub-object will keep track of all active memory regions
and handle memory read/write operations from the CPU.
A memory region is currently represented by a virtual Region object
that can implement arbitrary behavior by overriding read/write ops.

Loading a page with iframes could lead to a scenario, where the iframe
document finished layout prior to the main frame beeing laid out
initially. This caused a crash/assertion of the browser.
This should enable to destinguish between IFrame, Reload and Navigation
motivated loads in order to call the appropriate hooks.
This change is motivated as loading the IFrame test page causes the
IFrame url to be added to the history and shows up as the current
browser location bar.
This introduces a new X86 CPU emulator for running SerenityOS userspace
programs in a virtualized interpreter environment.
The main goal is to be able to instrument memory accesses and catch
interesting bugs that are very hard to find otherwise. But before we
can do fancy things like that, we have to build a competent emulator
able to actually run programs.
This initial version is able to run a very small program that makes
some tiny syscalls, but nothing more.
Links which do not have the "file" protocol (most commonly links to
external websites - http and https) are now not treated as file paths
anymore but instead handled by Desktop::Launcher.
The same applies to files outside of /usr/share/man.
Fixes#2727.
I saw this assertion fire once and I don't know how I made it happen,
but it seems fine for client-less windows to become active, they just
don't have a menubar to install.
We now have BlockResult::WokeNormally and BlockResult::NotBlocked,
both of which indicate no error. We can no longer just check for
BlockResult::WokeNormally and assume anything else must be an
interruption.
This code was previously relying on the PageView::on_load_start hook
firing synchronously when calling PageView::load(). This was not
happening with WebContentView, so it broke the back/forward history.
Instead, we now differentiate between history navigations and normal
loads in Tab::load(). History navigations don't push new entries into
history, but instead just move the history pointer.
This adds a new 32x32 Help application icon, a new open book icon,
copies the current book icon as Help's 16x16 icon, and updates
the Help application file to reflect these changes.
