I have never followed up and pushed for it. Maybe now is an opportune
moment to resume that effort=E2=80=A6

There is actually one much more grave issue in the Darwin port
of Drawterm that happens when the cursor is updated frequently.

Try navigating to a website with netsurf and hover over links
so the cursor changes frequently. Very likely you run into
a SEGFAULT. This happens on OSX Catalina and BigSur.

Here is the fix for it:

mac: fix SEGFAULT during cursor updates
=E2=80=A2 https://github.com/1g0rb0hm/drawterm/commit/01a3a73ebebfd765918f6104e5= 8154e7a7f56cff

Will resurrect the patches and resubmit them, the one with the
simulated buttons as well as the fix for the SEGFAULT.

BTW.=C2=A0 if you are interested in having Audio via Drawterm on OSX you might be interested in this one (thanks to Tony Mendoza
https://github.com/tmendoza/drawterm-maco= s-audio):

=E2=80=A2 https://github.com/1g0rb0hm/drawterm/commit/9dbda7617c22f4efe4bb58224b= d5d99ce36da8e7
