Unlike H264/H265, AV1 contains no fields to crop encoded output
to specific sizes.
AMD's hardware cannot handle encoding of unaligned dimensions for
AV1, hence it codes 1920x1080 as 1920x1088.
Add side data to crop the output back to the original dimensions.

This format is useful for doing certain lossless transforms on images,
RCT in particular, which require you to escalate the size from 16 to

APIchanges will be done alongside when comitting.

When converting a two-minute 3840 x 2160 video to a GIF file,
the viewing duration is shorter than the source duration when you use ffmpeg -i,
which is due to data overflow,
which causes positive numbers to become negative after being assigned,

This commit implements a standard, compliant, version 3 and version 4
FFv1 encoder, entirely in Vulkan. The encoder is written in standard
GLSL and requires a Vulkan 1.3 supporting GPU with the BDA extension.
The encoder can use any amount of slices, but nominally, should use

It isn't immediately obvious what indexing this array does.
Use standard syntax instead.
