Basically I watched https://www.youtube.com/watch?v=HsOKwUwL1bE and figured having tools within rx to do LUT pixel art animations can be cool.

I wanted to hear if you will be interested in merging such a feature.

Here's the demo:

I got plans to improve the UX and allow exporting the lookup table, and the lookup-table animations in a standalone spritesheet.

* add `lt/on` `lt/set` commands to set view as each other's lookup
  textures
* add lookuptex.{vert,frag} shaders to render the lookup
* generate initial lookup table values in `lt/on` views
* had to refactor Renderer.view_data into RefCell values
  * so other views could be referenced during the redering.

Note this is a pretty alpha stage, just got the shader to work really.
More work is needed to pack this in a sane user experience.
Add vec2(1/512) to lookup uv calculated from texture to ensure we land
mid-pixel when sampling the final texture

@guysv not to butt in where i'm not wanted, but i might be interested in merging such a feature on https://github.com/lowagner/pim. i have made a ton of changes since rx went silent, however, so it probably won't be a simple copy paste. if you're interested in updating to the other style, you are more than welcome, but if not please leave this branch around for me to take notes on.
