7fb32b6682 LibGfx: Fix off-by-some in Painter::draw_scaled_bitmap_with_transform()
Before this, drawing a 1x1 bitmap scaled up to MxN would only fill
M/2 x N/2 pixel, due to source_point going outside (0, 0).

af633523af LibGfx/WOFF2: Tolerate incorrect totalSfntSize in WOFF2 header
The specification says that this value is for reference only, so we
should be able to load a file where this value is incorrect.

66c9696687 LibGfx: Add initial ISO BMFF parsing and a utility to print file info
Currently, the `isobmff` utility will only print the media file type
info from the FileTypeBox (major brand and compatible brands), as well
as the names and sizes of top-level boxes.

884d8b14ac LibGfx: Prevent out of bounds access when scaling small Bitmaps
Since the color interpolation requires two pixels in the horizontal and
vertical direction to work, 1 pixel wide or high bitmaps would cause a
crash when scaling. Fix this by clamping the index into the valid range.

Fixes #16047.

f391ccfe53 LibGfx+Everywhere: Change Gfx::Rect to be endpoint exclusive
Previously, calling `.right()` on a `Gfx::Rect` would return the last
column's coordinate still inside the rectangle, or `left + width - 1`.
This is called 'endpoint inclusive' and does not make a lot of sense for
`Gfx::Rect<float>` where a rectangle of width 5 at position (0, 0) would
return 4 as its right side. This same problem exists for `.bottom()`.

This changes `Gfx::Rect` to be endpoint exclusive, which gives us the
nice property that `width = right - left` and `height = bottom - top`.
It enables us to treat `Gfx::Rect<int>` and `Gfx::Rect<float>` exactly
the same.

All users of `Gfx::Rect` have been updated accordingly.

fb79fc0ba6 Tests: Add a basic ICC profile test
icc-v4.jpg is Meta/Websites/serenityos.org/happy/3rd/bgianf.jpg.
There are a whole bunch of jpgs with v4 color profiles and I just picked
one fairly arbitrarily. It looks like a fairly standard v4 matrix
profile that in this form is also present in many jpgs taken by mobile
phone cameras. It uses parametric curves.

icc-v2.png is based on ./Documentation/WebServer_localhost.jpg since
that is the only image in the repo with a v2 color profile. It also has
all kinds of interesting and somewhat exotic tags, such as an 'dscm' (an
Apple extension to have a description of type 'mluc', since normal
'desc' is required ot have type 'desc' in v2 files -- in v4, 'desc' has
type 'mluc') tag of type 'mluc' that actually contains data in several
languages and that exercises the non-BMP UTF-16BE decoder. It's however
still also a fairly standard v2 matrix profile, which uses 'curv'
instead of 'para' for its curves ('para' is v4-only).

I converted that jpeg file to png, and cropped most of the image
data to save on file size by running:

    sips -s format png --cropToHeightWidth 21 42 in.jpg --out out.png

b8b5e0f680 LibGfx: Move TestFontHandling over to input file approach in 8cfabbcd93
Rather than reading files out of /res, put them in a subfolder of
Tests/LibGfx/ and pick the path based on AK_OS_SERENITY.

That way, the tests can also pass when run under lagom.

As far as I can tell, that's not needed and never was.

ce2f1b845f Everywhere: Mark dependencies of most targets as PRIVATE
Otherwise, we end up propagating those dependencies into targets that
link against that library, which creates unnecessary link-time
dependencies.

Also included are changes to readd now missing dependencies to tools
that actually need them.

58797a1289 Tests: Remove all file(GLOB) from CMakeLists in Tests
Using a file(GLOB) to find all the test files in a directory is an easy
hack to get things started, but has some drawbacks. Namely, if you add
a test, it won't be found again without re-running CMake. `ninja` seems
to do this automatically, but it would be nice to one day stop seeing it
rechecking our globbed directories.

fd0dbd1ebf Tests: Establish root Tests directory, move Userland/Tests there
With the goal of centralizing all tests in the system, this is a
first step to establish a Tests sub-tree. It will contain all of
the unit tests and test harnesses for the various components in the
system.
