Thanks, I pushed it to the emacs-26 branch.

Please in the future make sure the 1st line of the doc string is not
longer than 79 characters, and is a full sentence.

Also, please fill the lines in the log entry to be shorter than 75
characters, not including the leading whitespace.  And include the bug
number in the log message.

(I modified your patch to fix all those issues.)

I didn't install this part, because pixel-scroll-mode is a new mode
and is mentioned as such in NEWS.  So everything about it is "new",
and there's no need to mention individual changes.
