Resolves #157
This is an EXPERIMENTAL new feature. It works fine (I think) on my machine, but has not been tested anywhere else. As this deals with a fair amount of unsafe code, FFI, and the GPU, it is slightly more prone to going wrong than most features. I've fixed all the crashes I've discovered and Ironbar no longer takes up enough vram to start locking up other processes, but you have been warned...
Currently this relies on
hyprland-toplevel-export-v1, which means currently only Hyprland is supported. Prior to merge, support forext-image-copy-capture-v1will be added, which is currently supported by Sway, COSMIC, Jay, and Treeland. Other compositors (Including Hyprland) should follow behind.This also relies on DMA-BUF being available, which allows for offloading all the image work straight to the GPU. Any modern GPU driver should work with this, but older ones may not be supported, and I've no idea about Nouveau.
This raises the minimum required GTK version to 4.14. As a result, CI is failing due to some deprecated GTK functions. It's also failing because I need to fix the feature flags (I'd recommend building with all features if you want to try this). Everything does build and run okay though.
