fa02d2a39b Rework the rendering model so that clients instantiate backing stores.
This makes interactive resizing work a lot better, althought it's still not
perfect. There are still glitches and unpleasant flashes of zeroed memory.

59b8183c4b WindowServer: Support resizing windows.
This is pretty limited and not entirely stable, but it does work! :^)

bf30502560 LibGUI: Implement enter/leave events (with WindowServer support.)
Windows now learn when the mouse cursor leaves or enters them.
Use this to implement GWidget::{enter,leave}_event() and use that
to implement the CoolBar button effect. :^)

9b71307d49 WindowServer: Support windows with alpha channels. And per-WSWindow opacity.
This patch also adds a Format concept to GraphicsBitmap. For now there are
only two formats: RGB32 and RGBA32. Windows with alpha channel have their
backing stores created in the RGBA32 format.

Use this to make Terminal windows semi-transparent for that comfy rice look.
There is one problem here, in that window compositing overdraw incurs
multiple passes of blending of the same pixels. This leads to a mismatch in
opacity which is obviously not good. I will work on this in a later patch.

The alpha blending is currently straight C++. It should be relatively easy
to optimize this using SSE instructions.

For now I'm just happy with the cute effect. :^)

9a39c01551 WindowServer: WSWindow can have a pointer to the client rather than an ID.
Since WSWindows are owned by WSConnectionClients, it's fine for them to just
reference the client directly.

640360e958 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 :^)

09aaa41e62 SharedGraphics: Rework GraphicsBitmap::create_kernel_only() into create().
And just use mmap() to allocate the pixels.

18210c606d Kernel: Remove GUIEventDevice.
It's no longer used since all communication now happens across sockets. :^)

bf58241c11 Port the WindowServer and LibGUI to communicate through local sockets.
This is really cool! :^)

Apps currently refuse to start if the WindowServer isn't listening on the
socket in /wsportal. This makes sense, but I guess it would also be nice
to have some sort of "wait for server on startup" mode.

This has performance issues, and I'll work on those, but this stuff seems
to actually work and I'm very happy with that.

5d30c6b00c WindowServer: Add WSClientConnection::create_bitmap().
There we go. Now WSWindow doesn't know about Process at all.

9ab9734da0 WindowServer: Add WSClientConnection::post_message().
This way WSWindow doesn't have to grab at the Process.

aa7947c889 WindowServer: Add WSClientConnection class to manage an individual client.
This makes both object lifetimes and object ID's a lot easier to understand.

f529b845ec WindowServer: Convert entire API to be message-based.
One big step towards userspace WindowServer. :^)

fbbf57b61c Rename GUI_Event to GUI_ServerMessage.
Now that communication is becoming bidirectional, "event" is no longer right.

c61f9eba61 WindowServer: Add a WSWindowType enum.
So far there's only Normal and Menu. Maybe we'll need more later.

43d9994d93 WindowServer: Oops, we have to keep processing WSMessages with !m_process.
Otherwise we'll never handle WM_DestroyWindow and the window sticks around.

443b043b49 WindowServer: Start implementing a menu system.
I'm going with a global top-of-the-screen menu instead of per-window menus.
The basic idea is that menus will live in the WindowServer and clients can
create menus via WindowServer requests.

5582a0a254 Kernel: When a lock is busy, donate remaining process ticks to lock holder.
Since we know who's holding the lock, and we're gonna have to yield anyway,
we can just ask the scheduler to donate any remaining ticks to that process.

11db8c1697 Add a simple close button ("X") to windows.
Clicking the button generates a WindowCloseRequest event which the client app
then has to deal with. The default behavior for GWindow is to close() itself.

I also added a flag, GWindow::should_exit_event_loop_on_close() which does
what it sounds like it does.

This patch exposed some bugs in GWindow and GWidget teardown.

0c38a4c30f WindowServer: Sever the WSWindow/Process link when the process dies.
This fixes a deadlock where the WindowServer would get stuck trying to
acquire a dead process's event stream lock.

069d21ed7f Make buttons unpress when the cursor leaves the button rect.
Implement this functionality by adding global cursor tracking.
It's currently only possible for one GWidget per GWindow to track the cursor.

9fa8d4e22f WindowServer: Rename the two painting phases.
Work now happens in terms of two messages:

    - WM_ClientWantsToPaint
    - WM_ClientFinishedPaint

This feels fairly obvious compared to the old Paint/Invalidate.

bba21adae3 WindowServer: Rename WSEvent to WSMessage.
Also do the same for WSMessageLoop and WSMessageReceiver. More to come.

86eae0f8df Let userland retain the window backing store while drawing into it.
To start painting, call:
gui$get_window_backing_store()

Then finish up with:
gui$release_window_backing_store()

Process will retain the underlying GraphicsBitmap behind the scenes.
This fixes racing between the WindowServer and GUI clients.

This patch also adds a WSWindowLocker that is exactly what it sounds like.

51595603bd WindowServer: Rename WSEvent subclasses WSFooEvent for consistency.
Add a WSWindowInvalidationEvent that carries a rect instead of having an
awkward single-purpose rect in WSEvent.
Flesh out WSKeyEvent a bit more.

291922b1af WindowServer: Show PID and window ID in title bars for now.
This is useful for debugging since I'm often wondering which process some
window belongs to (and what the window ID is.)

dad58db757 Add WindowActivated and WindowDeactivated events.

the window active state.

f7ca6d254d 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.
