Use case

Hello Brandon, thanks for your awesome work. We are currently playing around with flutter_gpu, and wanted to recreate line rendering from this article:

Note that I'm not experienced in shaders, so I might be wrong here. Is it possible to execute something like glDrawArraysInstanced via flutter_gpu?

Proposal

Add instanced draw support
