v0.3.2: Saves: after upgrading from 0.2.4–0.2.9 to 0.3.x, the first launch of a game no longer treats the save written back by the old version as a newly added save and replaces your current progress, and 14 more fixes

Saves: after upgrading from 0.2.4–0.2.9 to 0.3.x, the first launch of a game no longer treats the save written back by the old version as a newly added save and replaces your current progress. The disk space estimate no longer blocks computers that can complete the export: space is freed while the game image is written, and old iPhone packages count as reclaimable space. Mac: the game library can now be on an exFAT external drive. Windows: exports no longer fail when game resources can't be moved into shared storage, the original error is no longer cut off, and intermediate files are cleaned up after stopping when the library and data are on different drives. Adding a game no longer fails with "the cover could not be written to the library" (File exists); if the cover can't be written, the game is still added. Retrying a game deletion no longer removes another game's folder by mistake. Windows: S2Arm now starts normally when its data folder's permissions can't be tightened or when the data folder is a junction to your user folder. Windows: games with interface overlays no longer pick up another game's original files, so writing the game image no longer fails because of it. iPhone / iPad: on devices without BC texture compression support (A15 / A16 and earlier), games using the GL graphics layer no longer crash on launch. Installing to iPhone no longer gets stuck at 99%: it completes once the transfer finishes instead of waiting for the phone to unpack. iPad / iPhone: fixed a crash on every launch after the game was killed once during startup. iPhone: launching a game whose image hasn't finished transferring now asks you to install it to iPhone again instead of starting with no data. Windows: the progress bars for writing the game image, verifying source files and seeding show again on the export page. Lower memory use when exporting Unity games on computers with less memory: assets are unpacked one at a time, and the direct-library fallback no longer fails along with it. Mac and M-series iPad: a class of game threads in some games (mainly Switch 2 titles) is no longer scheduled at a lower priority, noticeably reducing long stutters.
