flo_draw VS thorvg

I've been working a 2D rendering toolkit that increasingly looks to me like it probably deserves a mention on these lists: https://github.com/logicalshift/flo_draw (but I'm not on Reddit...). Layers, vector sprites, dynamic textures and a streaming API that fits well with 'reactive' designs are amongst the features that make it stand out from what else is out there. It's super simple to get going too.

Started life as a rendering layer for FlowBetween so I could put in whatever looked like it was 'winning' later on but wound up writing my own renderer as there wasn't anything quite there yet. Still has that design so another unique thing is that it's possible to use the same API with whatever rendering layer you want.

Speaking of FlowBetween, one thing I have wanted to do for ages is to get rid of the platform-specific GUIs and use something universal. It should be easy because FlowBetween sends straightforward instructions to an independent GUI layer, but I keep bouncing off for a few reasons:

- it's a big ole task so I definitely want to pick something that's stable and also lets me hedge my bets in terms of being easy to migrate away from

If Rust's your language, I wrote a library that should be pretty good at 2D things: https://github.com/logicalshift/flo_draw - I wrote it while working on another project (FlowBetween) where I found debugging would be easier if I could just render something on-screen but rendering stuff on screen always required a ridiculous amount of setup.

It has some nice options for feeding its own output back into itself as it uses streams rather than callbacks so it's quite good for procedural rendering type tasks (the 'Wibble' example is a good place to start with that)

I've been working on one for a while now that's very slowly coming together: https://github.com/logicalshift/flowbetween if you're interested.

I've been building out some backend stuff lately so there's a bunch of new features waiting to go in. https://github.com/Logicalshift/flo_draw has some demonstrations of the sort of procedural animation features I'm planning on adding, for instance.

Please have a look at this one: https://github.com/thorvg/thorvg.

What took the most time was to find a way to draw everything at runtime in C++. I tried a lot of libraries but finally I chose ThorVG which offers features similar to SVG.

Was amazing contributing as an open source contributor to the Samsung team at https://github.com/Samsung/thorvg and https://github.com/Samsung/rlottie.

`rlottie` is used in Discord and telegram for animated stickers and `thorvg` is the work-in-progress next generation animated vector / static vectors technology.

Hope that animated vectors is important to more people.
