47edd6ae89 LibGfx: Remove all load_FORMAT_from_memory() decoder wrappers 
There are no more clients of these APIs, now that everyone has been made
to use ImageDecoderPlugin objects instead.

7cc50d614c LibGfx: Include Vector.h in PNGLoader.cpp 
This was being transitively included from Deflate.h on SerenityOS builds
but not on Lagom builds.

880fafd2c5 LibGfx: Use ImageDecoder in Bitmap::try_load_from_fd_and_close() 
Before this patch, both Bitmap and ImageDecoder had logic for guessing
which image codec to use for a chunk of data. Bitmap now defers to
ImageDecoder so that we only have to do this in one place.

There's room for improvement in the ImageDecoder heuristic, but that's
outside the scope of this change.

10add3f4c2 LibGfx: Remove load_FORMAT() image codec wrappers 
We had a bunch of old unused wrapper functions for each image codec that
would load a supported image with a given path. Nobody actually used
them, so let's just get rid of load_png(), load_gif(), etc.

a15ed8743d AK: Make ByteBuffer::try_* functions return ErrorOr<void> 
Same as Vector, ByteBuffer now also signals allocation failure by
returning an ENOMEM Error instead of a bool, allowing us to use the
TRY() and MUST() patterns.

5f7d008791 AK+Everywhere: Stop including Vector.h from StringView.h 
Preparation for using Error.h from Vector.h. This required moving some
things out of line.

235f39e449 LibGfx: Use ErrorOr<T> for Bitmap::try_load_from_file() 
This was used in a lot of places, so this patch makes liberal use of
ErrorOr<T>::release_value_but_fixme_should_propagate_errors().

d85d741c59 LibGfx: Deduplicate code in Bitmap::try_load_from_file() 
This can share logic with try_load_from_fd_and_close(), we just need to
open the file first. :^)

09cba7c780 LibGfx: Use ErrorOr<T> for Bitmap infrastructure used by ShareableBitmap 
This also allows us to get rid of the ShareableBitmap(Bitmap)
constructor which was easy to misuse. Everyone now uses Bitmap's
to_shareable_bitmap() helper instead.

applications not using the system palette colors can still attempt to
match the overall theme.

Specifically, this is to make it accessible to ThemeEditor, but there's
nothing about it that is especially window-specific.

094dc04695 LibGfx: Make Color::from_string() case-insensitive 
This function implements CSS color syntax, which is case-insensitive in
HTML contexts. Making it insensitive here means not having to remember
to do it in every user, (many of the HTML elements do not do this,) and
means they don't have to produce a lowercase copy of the input string
before passing it.

21b65de1ec LibGfx+LibWeb: Move "transparent" keyword into Color::from_string() 
It seemed odd to have this one color handled separately, when
`Color::from_string()` implements all other CSS colors.

1bc4a0d822 LibGfx: Restrict cleared area to GIF framebuffer 
Found by OSS Fuzz, long-standing issue
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=34824

The discovered testcase attempts to clear the framebuffer of size
1056x32 from the previous image, which has size 16416x32.

ee18912373 LibGfx: Implement copy-assign for Matrix 
This used to generate a warning about using a deprecated copy-assign,
default-generated by the compiler, and deprecated because we hand-
implement the copy-constructor. This warning is correct, since the
default-generated copy-assign may or may not be as efficient as memcpy.

This patch gets rid of the warning, and has either no performance impact
or a slightly positive one. If this turns out to be wrong, we should
probably also fix the copy-constructor.

aa180c821d LibGFX: Draw the ends of lines with non-standard thickness 
Lines are drawn using squares the size of the thickness, so if the
length of the line was not a multiple of the thickness, the end of the
line was not drawn correctly.
