Release 5.5.0

Also stops one benign libmpv message being logged as an error: `after
creating texture: OpenGL error INVALID_ENUM` comes from the GL driver, arrives
several times per playback start and per fullscreen toggle, and playback
continues regardless. Hundreds of lines a session buried the errors that
matter -- it is a debug line now.

Verified end to end on the real display with an actual video playing: ten tab
switches and four fullscreen toggles while frames were rendering, position
advancing throughout, the render context intact, no crash, and an empty error
log afterwards.
