I feel like I'm going to be the RGA guy from now on...
Summary
This is a follow up to #2983 using hardware RGA enabled by #2977.
f73203aabe355cc25e00693b4eb250513b3665b1onwards is the active change, dependent commits have been left in.This PR offloads panel rotation, scaling, and multi-layer compositing onto the RGA2 2D engine (via librga). Falls back to the stock Vulkan/GPU path when the RGA (or a required buffer format/kernel feature) isn't available.
It also adds the Wayland pieces needed to display a nested Wayland video client on-panel (Steamlink was the test case I used to build this part, but the code is generic to any client using these protocols).
Testing
About a month ago I was developing this with Steam x86 FEX, and this was good enough for software rendered CEF. The past week and a bit I've been bringing it up targeting the Steamlink app, which led to the Wayland video client additions.
Additional Context
It's a meaty amount of changes. Steamlink works great with this, I might return to getting Steam x86 running again. I'm happy to answer questions.
AI Usage
The code comments are generated by Copilot, there was a heck of a lot of scar tissue I had to crawl through when cleaning these up for PR and most of the comments I had originally left for myself, now they are a lot more verbose and more explainy as AI tends to do with comments. As a result, there's more comment lines then there are active lines of code (I did try to keep this as minimal as possible).
