I'll go back and set up a test program to look into this.  I needed some sign flips to make zoom work right on my machine -- but I'm feeding it into an OpenGL zoom parameter that may be counter intuitive.

Well, I wrote a small demo program (test/gestures.cxx). We can certainly improve it, but it works as expected (by me) on macOS with my latest changes in my private fork:

You can either use CMake or fltk-config to build the demo program (Makefiles not updated).

Changes: positive angles in FL_ROTATE_GESTURE are now clockwise.

FL_ZOOM_GESTURE is in this test version not compatible with the 1.3 version. This is intentional and will be fixed in a later version.

Have fun! Feedback would be appreciated.
