12120167a9 AK: Add ensure_capacity() for HashMap and HashTable. 
These functions make sure that the underlying table can accomodate at least
'capacity' entries before needing a rehash.

4fb2e5d8af SharedGraphics: Make Rect::shatter() return a Vector<Rect, 4>. 
We know that shatter() will never return more than four rects, so we can
use vector inline capacity to always avoid heap allocation here.

3654c33c56 GFilePicker: Add a preview pane on the right-hand side for image previews. 
Currently the preview pane is always open, but maybe it should be something
you can configure, or something that happens automagically.

5ba2dba392 FileSystemPath: Add a has_extension() helper. 
This code:

    if (path.string().to_lowercase().ends_with(".foo"))

Can now be written as:

    if (path.has_extension(".foo"))

9b86eb9fad WSCompositor: Allow a compose to bypass the timer when it first happens 
d66fa60fcf introduced the use of a timer
to coalesce screen updates. This is OK, but it does introduce update
latency.

To help mitigate the impact of this, we now have a second (immediate)
timer. When a compose pass is first triggered, the immediate timer will
allow the compose to happen on the next spin of the event loop (so, only
coalescing updates across a single event loop pass). Any updates that
trigger while the delayed timer is running, though, will be delayed to
that (~60fps) timer.

This fixes #103.

8df3e2516f CEventLoop: Make it possible to determine running/quit state without using exec() 
... by removing a redundant member that nothing uses (running), and
exposing whether or not quit has been requested.

bb288c1baf IDEDiskDevice: Implement basic DMA writes. 
This could share more code with reads, and generally be better. But it works
and it's considerably faster than PIO, so let's use it. :^)

d66fa60fcf WSCompositor: Use a timer to schedule compose rather than an event 
Really poor man's vsync. Still not actual vsync, but at least we won't
constantly spin buffers if we get many dirty rects.

9b2fb47136 GTextEditor: Take frame size into account when setting clip rect 
The ruler right does not include the (already translated) frame size.
Take that into account too, otherwise we overdraw the ruler.

Fixes #23.

9308ce071f Userland: Add a helpful little program for provoking different crashes. 
Currently supported crash types:

    -s : Segmentation violation
    -d : Division by zero
    -i : Illegal instruction
    -a : Abort

0cac84d6bd Kernel: Sending a signal to yourself should block until dispatch. 
By moving the sending (and receiving) thread into the BlockedSignal state,
we ensure that the thread doesn't continue executing until the signal
has been dispatched.

6ffcee9176 Kernel: Send more specific signals when crashing due to CPU exceptions. 
- For division by zero, send SIGFPE.
- For illegal instruction, send SIGILL.
- For the rest, default to SIGSEGV.

0fa098845f Shell: When a command is terminated by a signal, print signal description.

7c37ffd9d8 LibC: Let the string for SIGFPE be "Division by zero". 
That's really what we send this signal for, so let's call it that.

41ebb3eba3 WindowServer: Tweak window titlebar look somewhat. 
Add a subtle shadow to the titlebar text. Also make the titlebar one pixel
taller to fully accomodate the 90s "3D frame" effect. :^)

cca510162e GButton: Align the button text according to text_alignment(). 
Added a Rect::align_within(other_rect, alignment) helper that seemed useful.

75b0e5cce5 Ext2FS: Block #0 can terminate an inode block list early. 
We were already handling this for the indirect blocks, but the direct ones
would happily consider #0 to be a valid block list entry.

d12857fc36 LibGUI: Notify widgets when their enabled state changes. 
This is done by dispatching a (synchronous) "EnabledChange" event that can
be picked up in change_event(). Use this event to kick widgets out of their
"being pressed"-type modes if the user is interacting with them while the
state is programmatically changed.

Also, Launcher now does not use titlebars.
Only check if titlebar should be shown if the window type works with that.

149b7f92a7 Demos: Start working on a simple WidgetGallery app. 
It's good to have a place where we can try out all the different widgets.
This needs some more work on a nice layout, and should also include more
of the widgets. :^)

ad908f1395 WindowServer: Factor out compositing from WSWindowManager into WSCompositor. 
This is far from finished and the two classes are awkwardly grabbing at each
other's innards, but here's a first step in the right direction.
