thunderbolt: fix missing variable underscore for `enrolling`
The variable `this.enrolling` is a typo because it has not been defined
before and is also never used.
`this._enrolling` is what it was meant to be.

messageTray: Re-enable unredirection when banner is destroyed
The intention of commit 4dc20398 was to disable unredirection while
banners are shown, but the ::done-displaying signal currently used for
re-enabling unredirection is only emitted under some circumstances, so
it's possible that unredirection is left disabled indefinitely, whoops.
Fix this by tying disabling unredirection explicitly to the lifetime
of the banner actor.

st: Avoid integer overflow on unpremultiply
When computing the effective border color, we operate on colors with
premultiplied alpha to simplify the calculations, then unpremultiply
the result. However we miss a bounds check in the last check, so any
color component can overflow the allowed maximum of 0xff and shift the
result in unexpected ways.

StWidget: don't forget to invalidate the paint state if not on stage
If the actor is not on the stage yet (i.e. does not have a theme
node), but has a paint state cached, we currently fail to invalidate
it, which will lead to the actor painting with old contents once it
gets onto the stage.
This commit fixes the issue by changing our invalidation strategy;
previously we were looking at the widget's own theme node to determine
if it should be invalidated or not.
Now we look at the theme nodes of our cached paint states. When the
widget is mapped on stage, those are the same as the widget's own
theme node, but when the widget is not on the stage, we'll still be
able to invalidate them.
As part of this, we move the invalidation API to StThemeNodePaintState,
which is a more natural place for our use case.
iconGrid: Eliminate JavaScript for painting/picking
The only reason for `vfunc_paint` and `vfunc_pick` existing was to
implement a culling optimization. Although that optimization actually
made performance worse than none at all because it forced the painting
and picking cycles to spend more time calling into JavaScript.
Turns out we don't have to choose between native code and culling though.
Just reimplement the culling using native ClutterActor functions and we
get the benefits of both.
Performance on an i7-7700:
Moving the cursor over the icon grid:
Before: 70% CPU, 5.5ms per frame
After : 60% CPU, 4.5ms per frame
Scrolling the icon grid:
Before: 60% CPU, 4.4ms per frame
After : 50% CPU, 3.3ms per frame
In X11, pointer emulated touch events are replicated with normal PRESS, RELEASE
pair events which are generated by the server. Thus for a single tap we get:
- TOUCH_BEGIN -> TOUCH_END, PRESS -> RELEASE
This will cause st-button to send two "clicked" signals, instead of just one,
breaking extensions (like dash-to-dock) that show buttons in the main stage
which will be checked two times or that will receive the same signal two times.
