Implemented move_to_beginning_of_next(), move_to_end_of_next(),
move_to_beginning_of_previous() and move_to_end_of_previous() functions
for more correct word jumping than the move_to_xxx_span() methods that
were previously used.
We will now throw a RangeError in these cases:
* new TypedArray with >= INT32_MAX entries
* new TypedArray whose ArrayBuffer allocation size computation would
cause a 32-bit unsigned overflow.
This makes the browser a bit less annoying when testing local files,
since you no longer have to restart it for changes to take effect.
Longer-term we should have a proper way to decide which resources
are cacheable.
If we have a function as class extends value, we still cannot assume
that it has a prototype property and that property has a function or
null as its value - blindly calling to_object() on it may fail.
Fixes#5075.
blit() calls draw_scaled_bitmap() behind the scenes in scaled contexts,
and that doesn't like src_rect to be outside of the source bitmap's
bounds. Implicitly clip with the source rect, like the non-scaled
codepath already does.
Fixes#5017 even more.
Consider
draw_scaled_bitmap({0, 0, 10, 10}, source, {0, 0, 5, 5}).
Imagine wanting to split that up into two calls, like e.g. the
compositor when redrawing the background with damage rects. You really
want to be able to say
draw_scaled_bitmap({0, 0, 5, 10}, source, {0, 0, 2.5, 5})
but up to now you couldn't. Now you can.
This makes painting very low-res images (such as tile.png) in mode
"stretch" work much better.
A C++ source file containing just
#include <LibFoo/Bar.h>
should always compile cleanly.
This patch adds missing header inclusions that could have caused weird error
messages if they were used in a different context. Also, this confused QtCreator.
Application.h includes Widget.h which includes Application.h. I'm not entirely
sure what the semantics are in this case, but avoiding this seems to be the
safer approach. In this case, Widget does not actually use Application, so let's
just remove the unused include.
With this patch it is possible to create PNG files. Only minimal options
are supported. The PNG is created with one big IDAT chunk containing
only non-compressible DEFLATE blocks.
This allows us to implement mkstemp() with open() directly, instead of
first lstat()'ing, and then open()'ing the filename.
Also implement tmpfile() in terms of mkstemp() instead of mktemp().
It's less code, and blit() already handles scaled painters.
Fixes the window server asserting in highdpi mode with a centered
background image. Part of #5017.
draw_scaled_bitmap() has a clearer API (just source and dest rects --
blit_scaled() took those and scale factors and then ignored width and
height on the source rect and it was less clear what it was supposed to
do), and they do mostly the same thing.
The draw_scaled_bitmap() API takes an IntRect as source rect, so it's
currently not always possible to split a big draw_scaled_bitmap() into
two (or more) smaller draw_scaled_bitmap() calls that do the same thing
-- that'd require FloatRects. The compositor kind of wants this to be
possible, but there's already a FIXME about this not looking quite right
with the previous approach either.
draw_scaled_bitmap() handles transparent sources, so after this change
wallpapers with transparency will be blended instead of copied. But that
seems fine, and if not, the Right Fix for that is to remove the alpha
channel from wallpapers after loading them anyways.
As an added bonus, draw_scaled_bitmap() already handles display scale,
so this fixes window server asserts for background images that are shown
as "stretch" (#5017). The window server still asserts for "tile" and
"offset" for now though.
Calling draw_scaled_bitmap() here exposed a bug in it fixed by #5041.
Before that is merged, this change here will cause smearing on the
background image when moving windows around.
