- Image display position relative to top left of text display, instead of top left of terminal widget.
  Fixes a problem described here: https://bugs.kde.org/show_bug.cgi?id=449799
- Improve cursor positioning and scrolling after displaying an image
  - Now the cursor ends in the same place relative to image regardless of whether scrolling is needed.
  - If the image fills the whole width of the terminal, the cursor is placed at the start of the line after the image (kitty and iterm protocols).
- Keep images in place when resizing the window vertically
