Bangle_showClock: Set Bangle.CLOCK=1

[thyttan]

Background:
When moving from an app where e.g. widanclk (analog clock widget) is
in use to the clock with a Bangle.showClock call the widget will not
hide immediately.

The fix:
Makes it so widgets that should hide on clock are hidden immediately
when fast loading the clock, at the same time as the red back button
widget.

By 'not hide immediately' do you mean there's a glitch/flicker as the clock loads, or that it takes multiple seconds/minutes?

Because I'd have thought that when you load a clock, the clock itself should call Bangle.setUI( which will set CLOCK=1, and then it will call Bangle.load/drawWidgets after which should redraw. So if that's not happening it would be better to find out why as it might be some other issue.

Also, I'd have thought Bangle.load should delete Bangle.CLOCK anyway really - because if you're loading something that's not a clock then you don't want that to stay set

It stays on for some tenth of a second longer than the red back button.

Yes, that's not the issue. It just seems there is some time before everything is ready to redraw - at least on edgeclk. EDIT: The issue as I see it now is that the red back button hides before edgeclk draws.

I don't know how this work currently.

With Bangle.CLOCK=1 added to showClock (disregard the drawing bug on large sections of edgeclk):

Thinking some more, maybe instead the red back button should stay around until the dtlaunch screen is cleared and edgeclk is drawn. That would also mitigate the widgets hiding at different times I think. I get unsure of what the best approach is.
