Make it possible for userspace to alter window title/geometry.
...
I'm not in love with this syscall API but it allows me to make progress.

Support polling with select() by using a zero timeout.
...
Use this in WindowServer to avoid getting blocked in select() when
there are pending injected events.

Make it possible to invalidate only a portion of a window.
...
Use this in Terminal to only invalidate rows where anything changed.

Rework WindowServer to use select() in its main event loop.
...
The system can finally idle without burning CPU. :^)
There are some issues with scheduling making the mouse cursor sloppy
and unresponsive that need to be dealt with.

Tear out or duplicate what's unique for WindowServer from Widgets.
...
This turned into a huge refactoring that somehow also includes
making locks recursive/reentrant.

Slap an InterruptDisabler on gui$invalidate_window().
...
This is obviously not a permanent solution but it works now to allow
the windowing system to withstand invalidation spam.

Share GraphicsBitmaps between the windowing server and the client process.
...
This is pretty cool. :^)
GraphicsBitmaps are now mapped into both the server and the client address
space (usually at different addresses but that doesn't matter.)
Added a GUI syscall for getting a window's backing store, and another one
for invalidating a window so that the server redraws it.

Start refactoring the windowing system to use an event loop.
...
Userspace programs can now open /dev/gui_events and read a stream of GUI_Event
structs one at a time.
I was stuck on a stupid problem where we'd reenter Scheduler::yield() due to
having one of the has_data_available_for_reading() implementations using locks.

Let's use the existing Rect and Color types in the GUI API.
...
Any type that doesn't depend on indirect data can probably be used here.
