If Serenity is ever used for more than a few days, the user will be more likely to
want to interact with their home directory than just be dropped at '/'.
Also, we have a Welcome program. Spotlight it!
And finally, there was a missing newline in the build script.
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().
This was just an alias for "unix" that I added early on back when there
was some belief that we might be compatible with OpenBSD. We're clearly
never going to be compatible with their pledges so just drop the alias.
Previously we had /bin/sh, which might be bash but is run in POSIX mode
on some systems, causing read -r to not work correctly and inserting
newlines when encountering literal "\n" in the source.
Fixes#5040.
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.
