"self" is a way to refer to the global object that will work in both
a window context and a web worker context.
"frames" apparently used to return a list of frame objects according
to MDN, but it now just returns the window object.
And also mark strlcpy() and strlcat() with __attribute__((warn_unused_result)).
Since our code is warning-free, this ensures we never misuse those functions.
(Or are very sure about doing it when turning off the warning for a particular
piece of code.)
In case we know exactly how many bytes we're copying (and not copying a string
while limiting its length to that of a buffer), memcpy() is a more appropriate
function to call.
Also, fix null-terminating the %c pointer.
Now that LibJS's .prettierrc has been moved to the repository root (as
we start having .js files in /res), we don't need to keep a second,
identical copy for the LibWeb tests.
DateTime::create() takes a date/time in local time, but it set
tm_isdst to 0, which meant it was in local winter time always.
Set tm_isdst to -1 so that times during summer time are treated
in summer time, and times in winter time are treated as winter
time (when appropriate). When the time is adjusted backward by
one hour, the same time can be in winter time or summer time,
so this isn't 100% reliable, but for most of the year it should
work fine.
Since LibJS uses DateTime, this means that the Date tuple
ctor (which creates a timestamp from year/month/day/hours/etc
in local time) and getTime() should now have consistent (and
correct) output, which should fix#3327.
In Serenity itself, dst handling (and timezones) are unimplemented
and this doens't have any effect yet, but in Lagom this has an effect.
GIFLoader now uses a single frame buffer to cache the last decoded
frame. This drastically reduces memory usage at the small expense of
re-decoding frames on each loop.
RestoreBackground disposal mode is now a transparent fill to allow
background to show through.
RestorePrevious disposal mode now restores the previous frame.
In the StringModelEditingDelegate convenience class, we simply hook up
the escape key to editor rollback. This means you can cancel an ongoing
cell edit by pressing escape. :^)
This API allows the embedder of a view to decide which actions upon
the view will begin editing the current item.
To maintain the old behavior, we will begin editing when an item is
either double-clicked, or when the "edit key" (return) is pressed.
