- Don't add the bell to the archive to keep it small a simplify
licensing. Also bells seem to be rarely used with terminal emulators.
- Don't play the bell directly from the Terminal node by adding an
AudioStreamPlayer, but make it easy to tune the "bell" signal behavior
from the Terminal node so that only an AudioStreamPlayer node's play()
method needs to be connected to it.
- Keep the bell.wav sound around for testing/demo.
Currently tests only run on X11.64 platform.
But other platforms can be supported with a bit of effort.
Remove default bell sound as it does not play nicely with CI environment
that does not have sound card.
- 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.
