> Here is a second draft move_it_in_display_line_to_x, with compatibility for word-wrap and also horizontal scrolling the current line that erroneously returns MOVE_LINE_TRUNCATED when trying to reach a target X that is about 1,000 pixels from the beginning of the line.

Once again, please show either a recipe in "emacs -Q" or a stand-alone
code snippet, which demonstrate the issues you mention.  FWIW, I
couldn't find such vulnerabilities by code inspection.
