This fixes an issue for the magnifier that when the screen scaling is
increased to 2 the magnifier doesn't center around the cursor.
Since booting Serenity with multiple displays doesn't work at the moment
the rescaling is only added for the one display case.
This doesn't capture the whole picture as shorthands are not considered
in a careful way.
A very dirty hack is included to not try to resolve 'font' as the amount
of debug spam it generated ("No inital value found for...") was
unhelpful.
The algorithm is quite simple: You grab a 2x2 area of pixels around the
point you want from the source bitmap, and then linearly interpolate
between them based on how far they are from that point.
This works well when scaling up images, and moderately well when scaling
down - small details may get skipped over. The way GPUs solve this is
with mipmaps, which is not something I want to get into right now. (And
increases the memory usage per bitmap by 50%.)
I have not focused on performance, but this does reuse much of the
existing fixed-point calculation, and uses constexpr so that the
performance for nearest-neighbor should be the same as it was
previously.
Previously, getauxval() got the address of the auxiliary vector by
traversing to the end of the `environ` pointer.
The assumption that the auxiliary vector comes after the environment
array is true at program startup, however the environment array may
be re-allocated and change its address during runtime which would cause
getauxval() to work with an incorrect auxiliary vector address.
To fix this, we now get the address of the auxiliary vector once in
__libc_init and store it in a libc-internal pointer which is then used
by getauxval().
Fixes#10087.
Instead of firing up a network request and synchronously blocking for it
to finish via a nested event loop, we now start an asynchronous request
when encountering <script src>.
Once the script load finishes (or fails), it gets executed at one of the
synchronization points in the HTML parser.
This solves some long-standing issues with random unexpected events
getting dispatched in the middle of parsing.
This doesn't follow the exact spec steps but instead simply makes a
nested Core::EventLoop and spins it while a periodic timer tests the
goal condition.
The code here wasn't updated when a new file icons appeared, so double-
-clicking a cursor didn't always set it to the correct one.
Also, the cursor list is sorted alphabetically, by the file name.
So if a theme used a different file naming in Config.ini, then
the previous code would also be incorrect.
Here we will just take the bitmap icon from the model.
Closes: #10142
An IPv4 mapped IPv6 address consist of 80 "0" bits, followed by 16 "1"
bits, followed by the 32-bit IPv4 address.
Example of IPv4 mapped IPv6 address:
IPv4 address: 169.219.13.133
IPv6 address: 0000:0000:0000:0000:FFFF:A9DB:0D85
Simplified : ::FFFF:A9DB:0D85
Old situation:
Object.h defines Object
Object.h defines ArrayObject
ArrayObject requires the definition of Object
ArrayObject requires the definition of Value
Value.h defines Value
Value requires the definition of Object
Therefore, a file with the single line "#include <Value.h>" used to
raise compilation errors; certainly not something that one might expect
from a library.
This patch splits up the definitions in Object.h to break the cycle.
Now, Object.h only defines Object, Value.h still only defines Value (and
includes Object.h), and the new header ObjectDerivatives.h defines
ArrayObject (and includes both Object.h and Value.h).
At least `Value::operator=` didn't properly unref the `PDF::Object` when
it was called. This type of problem is removed by just letting `RefPtr`
do its thing.
This patch increases the memory consumption by LibPDF by 4 bytes (the
other union objects) per value.
This was required before commit 5f724b6ca1
when we were building LibC before libstdc++ headers were available in
the sysroot. However as noted in that commit, we never actually needed
to be building LibC before libstdc++, so we can go ahead and remove this
ancient hack.
The only use of this define was removed in commit
5f724b6ca1, over a year ago.
The define was there to prevent the LibC build we built before libstdc++
from complaining about missing libgcc symbols. However, as noted in that
commit, we never actually needed to build LibC at all.
The logic here is needed by InlineNode too. Moving it into a
`paint_all_borders()` function makes it available to them both, as well
as anyone else who wants it. :^)
Doing so was causing the background to be painted twice, which looks
ugly if the background is semi-transparent. The painting is a bit of a
hack, as some situations apparently relied on it. This commit is ripping
the band-aid off to find where those are and fix them. :^)
This patch adds a basic initial implementation of these API's.
Since LibWeb currently doesn't support workers, this implementation of
messaging doesn't bother with serializing and deserializing messages.
