Camera.twistLeft and Camera.twistRight don't trigger Camera.changed

[easternmotors]

I have been using Camera.changed when the position/orientation of the camera changes but it seems that both Camera.twistLeft(amount) and Camera.twistRight(amount) don't trigger an event (though it seems like it may rarely?).

The twist command doesn't change the position of the camera, only the orientation (from what I understand). Even though Camera.changed doesn't specifically mention if it only triggers on camera position change or both camera position and orientation change, Shift + Click + Drag (to my knowledge) only changes the camera orientation yet still triggers Camera.changed.

Camera.twistLeft(amount) and Camera.twistRight(amount) don't appear in the CHANGELOG but Camera.changed has been around for a while (Released as part of 1.23) so my thought was maybe it was introduced after the Camera.changed work was done?

Just wanted to verify this was a bug and not intended functionality.

I think this issue might need to be reopened, as above PR only seems to handle the case when camera is looking straight down.

Looking at any view where the camera isn't looking straight down still shows no camera changes when twistLeft/Right are called.
