Out of date commit msg: it's FMT_DELTA_TD16 that's supported.

Do the width/height check here instead of in print_touch_buffer.

Rather than doing this before showing the pattern, it is better to
have this as a prefix at the start of each line. It's more compact.

Space before ;

You can drop the index variable by just adding ', vbuf++' after the y++
and using *vbuf instead of vbuf[index]. You also need to use le16toh
since the vbuf contents is little endian.
