* test/lisp/mouse-tests.el (bug23288-use-return-value)
(bug23288-translate-to-mouse-2): Don't rely as much on details of the
implementation, so it also works with the new code.
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
* lisp/frame.el (ns-set-mouse-absolute-pixel-position): New
function (Lisp).
(set-mouse-absolute-pixel-position): Change it to call
`ns-set-mouse-absolute-pixel-position' on macOS.
* src/nsfns.m (Fns_set_mouse_absolute_pixel_position): New
function.
* src/nsterm.h (NS_PARENT_WINDOW_TOP_POS): Use the primary
screen's height as a base for calculating global coordinates.
* src/nsterm.m (frame_set_mouse_pixel_position): Fix it in macOS.
* test/lisp/mouse-tests.el (bug26816-mouse-frame-movement): Test
movement of mouse relative to frame.
If ‘mouse-on-link-p’ returns a string or vector, the first element
is to be used as new event. Translation to ‘mouse-2’ should only
happen if the return value is not a string or vector. See
docstring of ‘mouse-on-link-p’ and Bug#23288.
* lisp/mouse.el (mouse--down-1-maybe-follows-link): Process return
value of ‘mouse-on-link-p’ according to documentation.
* test/lisp/mouse-tests.el (bug23288-use-return-value)
(bug23288-translate-to-mouse-2): Tests for Bug#23288.
