e7cddda7e1 LibGfx: Allow passing an ideal size to image decoders 
The ideal size is the size the user will display the image. Raster
formats should ignore this parameter, but vector formats can use
it to generate a bitmap of the ideal size.

da394abe04 LibGfx+Fuzz: Convert ImageDecoder::initialize to ErrorOr 
This prevents callers from accidentally discarding the result of
initialize(), which was the root cause of this OSS Fuzz bug:

ddc2cc886b LibGfx/WebP: Redo error handling 
Most places used to call `context.error()` to report an error,
which would set the context's state to `Error` and then return an
`Error::from_string_literal()`.

This is somewhat elegant, but it doesn't work: Some functions this
code calls returns ErrorOr<>s that aren't created by `context.error()`,
and for these we wouldn't enter the error state.

Instead, manually check error-ness at the leaf entry functions of the
class:

1. Add a set_error() helper for functions returning bool
2. In the two functions returning ErrorOr<>, awkwardly check the error
   manually.  If this becomes a very common pattern, maybe we can add
   a `TRY_WITH_HANDLER(expr, error_lambda)` which would invoke a
   lambda on error. We could use that here to set the error code.

No real behavior change (except we enter the error state more often
when something goes wrong).

animations.
