Images sent with the iTerm2 inline protocol (imgcat and friends) are
decoded (PNG, JPEG, GIF first frame) and drawn at the cursor, sized from
the width/height arguments in cells, pixels or percent (aspect kept,
never wider than the terminal); the cursor moves below so text
continues after them. They are anchored to the same stable line index
as the shell-integration marks, scroll with the text and are dropped
with the scrollback or on clear.
Remote data, so decoding is bounded (8192 px a side, 256 MiB
allocation), OSC bodies are capped at 16 MiB, inline=0 downloads are
ignored, and each terminal keeps at most 32 Mpx of images, oldest
first. Sixel and kitty graphics are not implemented.
