makes it ironically barely readable at all now to me since im used to typing with way less indents, lol. but i prettified it so you can read it

I think they want the namespace 'allo' as a prefix for their plugins so that's why it is laid out like that. I think it is using the Jimp Javascript library looking through the code.

it isn't ordinary css, it is Jimp, which is an imported javascript library that does a bunch of the common processing options of higher end image processing except in pure javascript. Back when i was learning code in droidscript, jimp was a droidscript plugin and i found it cool how it was entirely in JS yet did these things. So this is a port in of what they were porting in. Jimp takes image data, in this case from a blob created from the canvas element returned when a texttoimage is created, and outputs it to a file or canvas, in this case back to the same canvas. Jimp has a few more resizing and rotating and masking and concating images options not seen here.

and it is allo.img because i have actually created a global subobject on window, so window.allo.img to hold all these img manip functions. If I were to make a bunch to manipulate sounds, or pixi.js sprites, or three.js models, i would organize them like window.allo.sprites or window.allo.sound. then anything imported with one of my plugins that has to do with window will be in the neat window.allo box and not touching nor interfering with anything else. Because window doesn't need to be typed, the code comes out just allo.img.saturate. like vioneT said it's a namespace for what i make
