b918dcd4db LibGfx/TGA: Compute the number of pixels with a wider type 
Both width and height are stored in an u16 inside the TGA header,
computing the total number of pixel without using another type can
easily lead to overflows.

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=55309&q=serenity&can=2

0bdc93bca8 LibGfx: Fix double x_scale multiply when glyph kerning is cached 
This resolves a problem where the kerning value multiplied by the scale
is stored in the cache, even though the code retrieving the value from
the cache does not anticipate it to be scaled. As a result, it leads to
a buggy double multiplication by the scale.

806808f406 LibGfx: Provide a default implementation for animation-related methods 
Most image decoders that we have only support non-animated images,
providing a default implementation for them allows to remove quite some
code.

4291288a31 LibGfx: Remove ImageDecoderPlugin::initialize() 
No plugin is currently overriding the default implementation, which is a
no-op. So we can safely delete it.

An image with an incorrect header should fail at this step, so we have
to handle that without crashing.

This should have been done in 7b72bf29.

ff6d82c3e7 LibGfx/PNG: Decode the header in create() and remove initialize() 
This is done as a part of #19893. As `create()` is now the last user of

1bc7b0320e LibGfx: Approximate elliptical arcs with cubic beziers 
Unlike all other primitives elliptical arcs are non-trivial to
manipulate, it's tricky to correctly apply a Gfx::AffineTransform to
them. Prior to this change, Path::copy_transformed() was still
incorrectly applying transforms such as flips and skews to arcs.

This patch very closely approximates arcs with cubic beziers (I can not
visually spot any differences), which can then be easily and correctly
transformed in all cases.

Most of the maths here was taken from:
https://mortoray.com/rendering-an-svg-elliptical-arc-as-bezier-curves/
(which came from https://www.joecridge.me/content/pdf/bezier-arcs.pdf,
now a dead link).

8d4f90df4e LibGfx: Pass angles as floats to Path::elliptical_arc_to() 
These are stored as floats internally and other parameters are
FloatPoints, so taking doubles is a little inconsistent. Doubles are
needed for the endpoint -> center parametrization conversion, but that
does not need exposing in the API.

This matches the behavior of other decoders, and ensures just getting
