8f842375a2 LibHTML: Implement the <hr> element 
This also meant I had to implement basic support for the border-styles
"inset" and "outset". If it's neither of those, we default to "solid".

53fae2af4f LibHTML: Implement basic border rendering 
We currently assume the border-style is solid, and simply draw a box
around the padded LayoutNode rect. :^)

    <div style="color: #ff0000">This is red!</div>

Pretty neat :^)

8f45a259fc ByteBuffer: Remove pointer() in favor of data() 
We had two ways to get the data inside a ByteBuffer. That was silly.

dd696e7c75 LibM: Fix Toolchain build 
We can't rely on libstdc++ inside LibC or LibM, since these libraries
are part of the Toolchain bringup build.

ed39e0f6f7 LibHTML: Non-element (Text) Nodes should get style from their parent 
Text nodes don't have style of their own, so just inherit all the style
from the parent element.

b94c7665a9 LibHTML: Add a way to get a Document's title 
You can now query Document::title() to get a String containing whatever
is inside the document's <title> tag.

In support of this, this patch adds the <html>, <head> and <title>
elements.

f38b0f667e LibHTML: Implement basic HTMLElement.title support 
We now show a tooltip for the hovered node's enclosing HTML element's
title attribute, if one is present.

This patch also adds HTMLHeadingElement. The tags h1-h6 will now create
the right kind of objects.

92aae72025 LibHTML: Detect link clicks 
Clicking on a link in an HtmlView will now call on_link_click(String)
if present, allowing you to implement basic hypertext navigation. :^)

b477aff843 LibHTML: Detect hovering over links 
HtmlView now calls Node::enclosing_link_element() to find the nearest
ancestor <a> element.

This patch also adds HTMLElement and HTMLAnchorElement.

754e6e0f67 LibHTML: Add LayoutNode::document() for easy access 
Every LayoutNode indirectly belongs to some Document. For anonymous
LayoutNodes, we simply traverse the parent chain until we find someone
with a Node from which we can get a Document&.

13860e4dd8 LibHTML: Make hit testing work for LayoutText 
LayoutText can't simply rely on its LayoutNode::rect() for hit testing.
Instead, we have to iterate over the individual runs and see if we're
hitting any of them.

Also, LayoutNode::hit_test() now always recurses into children, since
we can't trust the rect() to tell the truth (inline rects are wrong.)

aac8b091a4 LibDraw: Implemented support for more PNG formats (#614) 
- Implemented support for more PNG formats including 16-bit per channel
  and 8-bit indexed with palette.
- Made the library a little more resistant to crashes by returning
  false for known but unsupported formats.

3de4b99dc3 LibHTML: Implement naive hit testing 
We don't have proper line boxes yet, so we can't easily hit test
inline text.

fb4702dd49 LibHTML: Add virtual Node::tag_name()

"hey, what kinda thing is this Node?"

a768724270 LibHTML: Make <a> tags blue and underline by default 
In the future, this should only apply to "a:link", but since we don't
have pseudo-classes yet, all "a" tags will do for now.

62cbaa74f3 LibHTML: Respect the CSS "color" property for text 
Also remove the color values from the ComputedStyle object and get them
via StyleProperties instead.

At the moment, we only handle colors that Color::from_string() parses.

6ec625d6f3 Userland+LibHTML: Add the html command 
This is a simple command that can be used to display HTML from a given
file, or from the standard input, in an HtmlView. It replaces the `tho`
(test HTML output) command.

9f8d776c70 LibHTML: Implement LayoutInline::layout() 
This currently uses a gross hack where it subtracts 11px from the
previous sibling bottom to calculate its top. This should be fixed
by switching to a proper two-phase line layouting model, were we
first distribute inline elements into lines and figure out their
horizontal positions and heights; then compute the needed line
heights and position inline elements there vertically.
