7dc5a3ead8 LibGUI: Rewrite layout system in terms of min and max sizes
This patch removes size policies and preferred sizes, and replaces them
with min-size and max-size for each widget.

Box layout now works in 3 passes:

    1) Set all items (widgets/spacers) to their min-size
    2) Distribute remaining space evenly, respecting max-size
    3) Place widgets one after the other, adding spacing in between

I've also added convenience helpers for setting a fixed size (which is
the same as setting min-size and max-size to the same value.)

This significantly reduces the verbosity of widget layout and makes GML
a bit more pleasant to write, too. :^)

d8474d80f2 PixelPaint: Save and load to and from disk
Store a PixelPaint project in a .pp file (as there doesn't seem to
be any real standard on this). It's a very simple json file that
contains the bitmap as a base64 encoded bmp.

1c27568ab0 PixelPaint: Undo and redo actions
The most used feature of any image editor, undo. Each tool now
notifies the ImageEditor that they completed an action, where
it'll take a snapshot if its current state.

For now, a snapshot is just a copy of the whole image and its
layers. There's a hard limit on the amount of actions it stores.

through a panel on the right side.

The tools I've added properties for are:

Pen:
	Thickness

Brush:
	Size
	Hardness

Spray:
	Thickness
	Density

Bucket:
	Threshold

95434d70ed LibGfx: Allow specifying a separate source bitmap for Filter::apply
By allowing to specify a separate source bitmap when calling Filter::apply
the same filter can be applied to multiple areas, and also doesn't need
to use a temporary bitmap. This also enables us to apply the filter to
multiple regions properly, even if they are (almost) adjacent.

If no separate source bitmap is supplied then a temporary bitmap is still
necessary.

da8d87c297 LibGfx: Make Filter::Parameters more light-weight
By moving the Bitmap and Rect out of Filter::Parameters we can re-use
the parameters more efficiently, allowing the filter to be applied
to many bitmaps without having to re-create the filter every time.

27bd2eab22 LibWeb: Require parent window argument for MessageBox
Since the vast majority of message boxes should be modal, require
the parent window to be passed in, which can be nullptr for the
rare case that they don't. By it being the first argument, the
default arguments also don't need to be explicitly stated in most
cases, and it encourages passing in a parent window handle.

Fix up several message boxes that should have been modal.

ca93c22ae2 LibGUI: Turn GUI::Application::the() into a pointer
During app teardown, the Application object may be destroyed before
something else, and so having Application::the() return a reference was
obscuring the truth about its lifetime.

This patch makes the API more honest by returning a pointer. While
this makes call sites look a bit more sketchy, do note that the global
Application pointer only becomes null during app teardown.

de85cd0907 PixelPaint: Start working on a custom layer list widget
Instead of using a TableView to show the layer stack, let's build a new
custom widget for this purpose and give it some neat features!

This patch also introduces an ImageClient interface for Image to notify
interested parties about things happening. The LayerListWidget is the
first ImageClient and listens for "layer added" and "layer removed"
notifications. :^)
