- lower drawImage pressure by drawing neighboring tiles at once

- DECSET/DECRST handlers
- calc size limit on incoming bytes
- stub type ICoreTerminal
- hook for fontSize changes
- round cell size to full pixels to avoid nasty offsets
- recreate bitmap also for original
- store image info in extended attrs
- create image on cell border aligned canvas
- extract BG colors from terminal for P2
- several internal types

- move csi handler to addon
- simplify disposing
- implement reset handlers
- implement cursor modes: scrolling off | right | below
- fix missing LE conversion of default BG

- update sixel package
- fix bug in image eviction
- API tests for cursor positioning and eviction
- fix eslint OOM

- wipe images on alternate buffer on switch
- better memory accounting
- tile count with inline eviction
- manual tile count tracking on alternate
- eviction tests

- early iTerm2 version
  - basic support implemented (no size parameter respected yet)
  - needs several changes to underlying datastructures:
    - canvas not suitable as storage format, needs Bitmap for
      easy and speedy async construction --> rework ImageStorage
    - proper separation of sync vs. async:
      getting image dimsensions must be sync to parser handler,
      everything else can be offloaded (image decoding)
      --> make base64 decoder streamline to return widht/height early
      --> investigate same for SIXEL handler
- early stub of enhanced image protocol in ImageHandler.ts
  based on discussion in terminal-wg

- handle worker loading error gracfully
  - turn sixel actions to NOOPs
  - change feature reporting to not supported
- worker manager tests
