Elyra Conductor v0.8.3

Changed

• Much smoother terminals with multiple agents. Terminal rendering now uses the GPU
  (WebGL), and PTY output is coalesced into one write per animation frame. Running several
  repaint-heavy TUIs at once (e.g. multiple Elyra agents) no longer makes the window
  sluggish. Falls back to the DOM renderer if a GPU context is unavailable.

Fixed

• Closing a terminal tab no longer garbles the remaining terminal. Hidden panes are no
  longer measured at 0×0 and shrunk — they keep their size and re-fit only when visible.
