38dd4168be LibGfx/ICO: Decode the header in create() and remove initialize() 
This is done as a part of #19893.

8d907b6535 LibGfx/PNG: Don't use a loop to read chunks in decode_png_ihdr() 
This chunk is the first one, so we can remove that loop.

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
`decode_png_ihdr()`, we can easily make it return an `ErrorOr`.

8946c0c104 LibGfx/DDS: Don't double-check the magic number

7b72bf2910 LibGfx: Don't assume that image decoder plugin creation succeeds 
An image with an incorrect header should fail at this step, so we have
to handle that without crashing.

bebfb81c85 LibGfx/TinyVG: Parse and ignore line_width in paths 
TinyVG allows varying the line width along a path, this is not supported
in LibGfx so we just ignore this (but still need to parse the field).

500097de82 LibGfx/GIF: Decode the header in create() 
Again, header includes the logical screen descriptor here. This is done
as a part of #19893.

294217586b LibGfx/GIF: Move the code to read the header to its own function 
By header, I include the logical screen descriptor here, so all the
information that is not specific to each frame.

1192e46c09 LibGfx/GIF: Don't read the header twice 
This is already done in `load_gif_frame_descriptors()`. As the method
`initialize()` is now empty, we can delete it.

57c81c1719 LibGfx: Lazily load TinyVG image data 
This matches the behavior of other decoders, and ensures just getting
the size (e.g. for the `file` command) does not read the whole file.

753cf04be8 LibGfx: Allow requesting vector graphic frames from ImageDecoder 
Only supported for plugins that set is_vector() to true. This returns
the frames as Gfx::VectorGraphics, which allows painting/rasterizing
them with arbitrary transforms and scales.

5fd1ee0365 LibGfx/QOI: Remove useless parameters from member functions 
Both `decode_[header,image]_and_update_context()` used to take a
`Stream&` as parameter, but they are always called with the field
`m_context.stream` so no need to take it as a parameter.

8c13b83a84 LibGfx/PNGWriter: Use a better limit for scanline capactiy 
One scanline is width pixels long, not height pixels.

No measurable performance difference, but it annoys me every time I look
at this file.

f3ff9c26bc LibGfx/PortableFormat: Simplify the State enum 
This enum used to store very precise state about the decoding process,
let's simplify that by only including two steps: HeaderDecoder and
BitmapDecoded.

f7f9f1f47f LibGfx/PNG: Make invalid sRGB chunk size non-fatal 
https://www.haiku-os.org/images/bg-page.png has a size of 0 for
example.

Just ignoring the chunk instead of assuming that the image is sRGB
and has Perceptual rendering intent matches what libpng does
(cf `png_handle_sRGB()`), so let's do that too.

(All other chunk handlers are still strict about size.)

babe924da1 LibGfx: Provide a default implementation for ImageDecoder::initialize 
In order to ease the removal of this function, let's provide a no-op
default implementation so decoders can stop implementing it one by one.

The adobe specification doesn't even consider JPEG images with a single

grayscale images.
