e7fe377501 LibGfx: Use a Stream to read WOFF font data 
This lets us read structs directly from the data, instead of having to
construct them from manual offsets.

a9208a18ca LibGfx/BMPLoader: Make sure height passed to Gfx::Bitmap is positive 
BMP files encode the direction of the rows with the sign of the height.
Our BMP decoder already makes all the proper checks, however when
constructing the Gfx::Bitmap, didn't actually make the height positive.

Boog neutralized :^)

95bf6ddb8e LibGfx: Fix serializing Gfx::Bitmaps 
a396bb0 removed the palette field but did not update the allocation size
in `Bitmap::serialize_to_byte_buffer()`. This led to a few crashes (I
noticed this from a drag/drop crash in the file manager).

Fixes #21434

a396bb0c0b LibGfx: Remove indexed palette formats from Bitmap and Painter 
Nobody was actually using these formats anymore, and this simplifies
and shrinks the code. :^)

bcbaad0b1d LibGfx: Make BMP decoder always produce BGRA8888 or BGRx8888 bitmaps 
This was the only remaining codec that produced IndexedN bitmaps.
By removing them, we'll be able to get rid of those formats and simplify
the Bitmap and Painter classes.

80e756daef LibGfx: Load BitmapFont data more safely 
Previously, `load_from_memory()` just took a raw pointer to the data,
and then manually calculated offsets from that pointer. Instead, let's
use the MappedFile we already have, to stream in the data, to make
things a bit safer. We also now check that the entire file's data was
read, since if there was data left over, then either the file is bad or
we've done something wrong.

I've moved the code directly into `try_load_from_mapped_file()` since
`load_from_memory()` was only called from there. The extra indirection
wasn't adding anything.

would read past the end of the stream. We now return an error in such
cases.

563bb9d20c ICC: Implement Profile::to_pcs() for grayscale colors 
There's probably a nicer way of doing this where we don't need to expand
the gray value into a full Vector3, but for now this is good enough.

Makes PDFs written by macOS 13.5.2's "Save as PDF..." feature show up.

062e0db46c LibCore: Make MappedFile OwnPtr-based 
Since it will become a stream in a little bit, it should behave like all
non-trivial stream classes, who are not primarily intended to have
shared ownership to make closing behavior more predictable. Across all
uses of MappedFile, there is only one use case of shared mapped files in
LibVideo, which now uses the thin SharedMappedFile wrapper.

bbf66ea055 LibGfx: Remove maximum size limit for decoded images 
It is unlikely this is needed anymore, and as pointed out things should
now safely return OOM if the bitmap is too large to allocate.

Also, no recently added decoders respected this limit anyway.

2cd89531f9 LibGfx: Add FontDatabase::for_each_typeface_with_family_name() 
Some clients (e.g LibWeb) want to look up typefaces by name. Since we
already store typefaces in a HashMap keyed by family name, let's also
have a nice & fast API that takes advantage of this.
