Software renderer

[edouardparis]

This issue is to measure interest and demonstrate support for the development of a software renderer for Iced

As described in the roadmap, two choices may be considered:

• skia, existing issue: Skia support. #520
• piet

Very interested in a 2d renderer. Would prefer piet as it is a rather lean dependency compared to the monstrous skia. I fear that the systems that have no 3d acceleration have a big overlap with the systems that skia does not compile on. ;)

If I see this correctly, @hecrj already wrote some glue code to combine winit with piet. Has the iced / piet approach ever been evaluated?

[hecrj]

@gonsor Yes! I'm actively working towards an iced_piet renderer.

piet-window was an experiment and posed a bunch of challenges. Instead of using winit, the plan is to build an iced runtime on top of druid-shell.

The work in #1110 set the foundations to make this road easier. We are getting there!

Hello there. A friendly ping to learn what's the status of this, given It's been a year since the last comment. It would be very useful for downstream applications to not require their users to have 3D drivers/libraries.

This will land soon, together with the work from #1697.

In the end, I chose tiny-skia since it seems the best viable option and we already depend on it for SVG rendering!

Work is happening in the feature/software-renderer branch.
