91a4b60d66 Painter: Templatize the inner loop of draw_scaled_bitmap(). 
Use templates to specialize draw_scaled_bitmap() so we don't have to blend()
for source without alpha, and also inline the GraphicsBitmap::get_pixel()
logic so we don't have to branch on the bitmap format on every iteration.

This is another ~30% speedup on top of the previous changes. :^)

5c4b421d56 GTabWidget: Highlight tab buttons when hovered. 
The active tab's button doesn't get highlighted, since the highlight is
supposed to indicate that the widget can be interacted with.

cb3e150983 GraphicsBitmap: Add non-const overload of bits(). 
This is clearly useful, I don't know why I thought it wasn't.

61e3ecec79 GraphicsBitmap: Add a new "Indexed8" format that uses a 256-entry palette. 
These bitmaps should only be used as a source bitmap, we won't support
painting into them using Painter. You can however manipulate the raw
pixel data. :^)

cec16105cc Make sure all GraphicsBitmap scanlines are 16-byte aligned. 
This is a prerequisite for some optimizations.

9e5ad25188 GTabWidget: Paint a frame around the container part of the widget. 
Then make the active tab stand out by punching a hole in the frame below
its button.

f3aec1a0d9 Painter: Re-enable diagonal draw_line(). 
This code still needs clipping, but the basic concept works. It was disabled
since before the kernel had floating point support.

8f81a3f9dd LibGUI+WindowServer: Make it possible to have checkable GActions. 
They show up as checkable GButtons in GToolBar, and with (or without) check
marks in menus.

There are a bunch of places to make use of this. This patch only takes
advantage of it in the FileManager for the view type actions.

7dc4078a73 SharedGraphics: Add is_right_text_alignment(TextAlignment) helper. 
This seems a tad bit more future-proof than manually checking all the valid
right-side TextAlignment values in clients.

58240fdb33 Do a pass of compiler warning fixes. 
This is really making me question not using 64-bit integers more.

7efd61fcf5 WindowSerer+LibGUI: Send multiple rects in invalidation/flush messages. 
This patch moves to sending up to 32 rects at a time when coordinating the
painting between WindowServer and its clients. Rects are also merged into
a minimal DisjointRectSet on the server side before painting.

Interactive resize looks a lot better after this change, since we can
usually do all the repainting needed in one go.

5eedb22834 Sprinkle use of AK::Vector in various places. 
Some of these are less helpful than others. Avoiding a bunch of mallocs
in the event loop wakeup code is definitely nice.

86361d3d45 WindowServer: Improve the look of menus. 
This patch makes menus stand out a bit more from their background by using
the same kind of shading that Windows 2000 had.

5e0577a042 Introduce LibCore and move GElapsedTimer => CElapsedTimer. 
I need a layer somewhere between AK (usable both by userspace and kernel)
and LibGUI (usable by userspace except WindowServer.) So here's LibCore.

30e2d62c38 WindowServer: Factor out some parts of compose(). 
The main compositing loop was getting pretty unwieldy. Break out some parts
into functions so it's more understandable.

4ab0cd5d4c LibGUI: Move frame painting from GFrame to StylePainter. 
This way it can be used by others who might not have a GFrame object.

4533539e8a 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 "..."

c02c9880b6 AK: Add Eternal<T> and use it in various places. 
This is useful for static locals that never need to be destroyed:

Thing& Thing::the()
{
    static Eternal<Thing> the;
    return the;
}

The object will be allocated in data segment memory and will never have
its destructor invoked.

2334ffcbf8 WindowServer: Add a WSCursor class (a bitmap and a hotspot.) 
Also import a bunch of cursors I drew. Only the default ("arrow") cursor is
ever used so far.

9538c06a45 LibGUI: Add a simple GSplitter container widget. 
This allows you to put multiple widgets in a container and makes the space
in between them draggable to resize the two adjacent widgets.
