Painter: Add text elision support (only right-hand side supported.)
...
Some window titles didn't fit on the taskbar buttons, so I needed a way
to collapse the remaining part of the text into "..."

Kernel: Add Inode::truncate(size).
...
- Use this to implement the O_TRUNC open flag.
- Fix creat() to pass O_CREAT | O_TRUNC | O_WRONLY.
- Make sure we truncate wherever appropriate.

AK: Make ByteBuffer's copy() and wrap() take void*.
...
This way we don't have to cast whatever we're passing to copy()/wrap().

Add a bold variant of Katica and make that the system's default bold font.
...
..and do some minor tweaks to the font rendering code.

More work on the variable-width font support.
...
Katica is now the default system font, and it looks quite nice. :^)
I'm gonna need to refine the GTextBox movement stuff eventually,
but it works well-enough for basic editing now.

Implement basic support for variable-width fonts.
...
Also add a nice new font called Katica. It's not used anywhere yet but
I'm definitely itching to start using it. :^)

It's nice to have a thin and a bold variant to complement each other.

Base: Import a new font, Csilla Thin (7x10).
...
I wanted to do a bitmap font with an odd number of columns for a while
and I finally got around to it. This really looks rather nice, so I'm
making it the default system font for now. :^)

I'm still feeling this out, but I am starting to like the general idea.

Move WindowServer to userspace.
...
This is a monster patch that required changing a whole bunch of things.
There are performance and stability issues all over the place, but it works.
Pretty cool, I have to admit :^)

Use modern C++ attributes instead of __attribute__ voodoo.
...
This is quite nice, although I wish [[gnu::always_inline]] implied inline.
Also "gnu::" is kind of a wart, but whatcha gonna do.

SharedGraphics: Don't eagerly commit mmap'ed font files in kernel.

Just let the page fault handler do its thing. Anytime we can avoid
loading some pages from disk, that's a good thing.

This was a constant source of stupid bugs and I kept postponing it because
I wasn't in the mood to write assembly code. Until now! :^)

Rename LizaBold to LizaRegular and LizaBlack to LizaBold.

LizaRegular is quickly becoming my favorite bitmap font. It's so pretty :^)

mmap all the font files!
...
Font now uses the same in-memory format as the font files we have on disk.
This allows us to simply mmap() the font files and not use any additional
memory for them. Very cool! :^)
Hacking on this exposed a bug in file-backed VMObjects where the first client
to instantiate a VMObject for a specific inode also got to decide its size.
Since file-backed VMObjects always have the same size as the underlying file,
this made no sense, so I removed the ability to even set a size in that case.

Make font loading use mmap().
...
This exposed a serious race condition in page_in_from_inode().
Reordered the logic and added a paging lock to VMObject.
Now, only one process can page in from a VMObject at a time.
There are definitely ways to optimize this, for instance by making
the locking be per-page instead. It's not something that I'm going
to worry about right now though.

Support font files.
...
This only works with the userspace build of SharedGraphics so far.
It's also very slow at loading fonts, but that's easy to fix.
Let's put fonts in /res/fonts/.

Start working on a simple graphical font editor.

Editing fonts by editing text files is really slow and boring.
A simple font editor seems like a good way to take LibGUI for a spin.
