- Use viewport as render target for terminal:
Terminal now only draws cells which changed since the last _draw() call.
A viewport is used with clear mode set to NEVER to cache previous draw
calls. The terminal node and viewport are wrapped by a GDScript Terminal
node which takes care of resizing the viewport scene, and forcing the
terminal to redraw all cells when necessary (i.e. on resize or theme
change).
Adds update_mode to terminal interface which can be set to one of:
- DISABLED: terminal will never be drawn
- AUTO: terminal will only draw the cells that changed, but
automatically redraw the full screen when necessary (for example,
when the size or theme changed).
- ALL: terminal will always draw every cell on every update. This is
the most reliable but least performant option.
- ALL_NEXT_FRAME: Will use update_mode ALL for the next _draw() call,
then change update_mode back to AUTO.
- Upgraded libtsm:
Includes changes from Fredrik Wikstrom (salass00)'s fork of libtsm.
- Don't require theme to be set.
Terminal will use default fonts/colors if no theme is set.
