Linux: SteamVR overlay support (#1299)
* fix: open folder and select item on linux * feat: linux wrist overlay * feat: linux hmd overlay * feat: replace unix sockets with shm on linux * fix: reduce linux wrist overlay fps * fix: hide electron offscreen windows * fix: destroy electron offscreen windows when not in use * fix: open folder and select item on linux * feat: cpu, uptime and device monitoring on linux * feat: native wayland gl context with x11 fallback on linux * fix: use platform agnostic wording for common folders * fix: crash dumps folder button on linux * fix: enable missing VR notification options on linux * fix: update cef, eslint config to include updated AppApiVr names * merge: rebase linux VR changes to upstream * Clean up * Load custom file contents rather than path Fixes loading custom file in debug mode * fix: call SetVR on linux as well * fix: AppApiVrElectron init, properly create and dispose of shm * Handle avatar history error * Lint * Change overlay dispose logic * macOS DOTNET_ROOT * Remove moving dotnet bin * Fix * fix: init overlay on SteamVR restart * Fix fetching empty instance, fix user dialog not fetching * Trim direct access inputs * Make icon higher res, because mac build would fail 😂 * macOS fixes * will it build? that's the question * fix: ensure offscreen windows are ready before vrinit * will it build? that's the question * will it build? that's the question * meow * one, more, time * Fix crash and overlay ellipsis * a --------- Co-authored-by: Natsumi <cmcooper123@hotmail.com>
