Mac multitouch rotation does not work after Log undocked

[goddard@…]

The following bug report has been submitted:
Platform:        macOS-10.16-x86_64-i386-64bit
ChimeraX Version: 1.2.5 (2021-05-24 04:13:57 UTC)
Description
If the log panel is undocked sometimes multitouch 2-finger drag on the graphics does not rotate the model.  Instead the 2-finger drag immediately gives the focus to the log and the graphics zooms as if multitouch is not enabled.

This does not always happen when the log is undocked.  One method that seems to reproduce it reliably is to start ChimeraX,  open a PDB model,  then try a single 2-finger vertical drag.  Bizarrely this sometimes zooms and sometimes it rotates.  If it zooms,  then drag the Log panel out,  click back into the graphics and 2-finger drag seems to always give the wrong zoom behavior with the focus going to the log.  If that very first 2-finger drag after opening a model rotates then dragging out the Log does not mess up future 2-finger drag rotations.

Possibly ChimeraX is enabling multitouch on the wrong window,  on the Log window instead of the graphics window?  It seems like when the first 2-finger drag in the graphics does a zoom multitouch is somehow not enabled yet.

[Tom Goddard]

This ticket came about from investigating ticket #5454 and #5455.

[Tom Goddard]

Even if the first 2-finger drag does a rotation, dragging out the Log still sometimes leaves 2-finger drag broken and giving focus to the Log. I only get the broken mode about 1 in 3 tries. And I see the same erratic reproducibility in the October 19 2021 daily builds as in the 1.2.5 release.

[Tom Goddard]

I am unable to reproduce this multitouch failure with my experimental Qt 6.2 version of ChimeraX.
