What problem does this solve or what need does it fill?

"Pixel-perfect rendering" is a hotly requested feature for retro games, or for more unusual use cases where very-direct control is desired.

What solution would you like?

We create a shader that does this, which is fed out of a resource that stores a screen_width x screen_height array of pixel data.

What alternative(s) have you considered?

None, but I don't know graphics well.

Additional context

bevy_retro by @zicklag has this functionality, but the license is very much incompatible with Bevy itself. Guidance would be lovely if you're willing to chime in <3
