Drawing text with Pango is quite expensive, and drawing text and also
blurring it is *really* expensive. To prevent us from drawing a lot of
text and then blurring it a lot is *really* expensive.
We now cache the blurred pixels for the last layout and shadow we made,
which means we can repeatedly draw labels with a blurred text-shadow
extremely fast.
To detect whether the shadow is up-to-date, we track the serial of the
PangoLayout alongside the radius of the box shadow. We don't support
inset shadows nor spread on text-shadow, so we don't need to track
these.
There is no need for a critical warning just because somebody
asked for a property that is not meaningful for the device.
Just document it as not useful for keyboard devices.
We get multiple notifications from the bookmark manager when
something changes. Every time, we reconstruct the sidebar contents
completely, by clearing the store. The bookmarks are added with
async calls though, and the code was forgetting to cancel outstanding
async requests, leading to multiple instances of the same bookmark
getting added. Use the cancellable we already have to prevent that.
This could be made much more efficient by not recreating the entire
sidebar quite so often (3-5 times for a single bookmark rename).

Parent is guaranteed to not be NULL. It can only ever be NULL for root
windows and root windows cannot be created with gdk_window_new() and
gdk_window_ensure_native() will exit early because they already are
native.
Also, both functions would crash a few lines below where parent gets
dereferenced.
I've noticed a missing image show up in my print dialog, where
the printer reported "printer-paused" as icon. Rearrange things
so we always fall back to "printer" for printer icons.
We still need to possibly scan the toplevel after selecting
a widget, since we don't monitor the list of toplevels, so
the window may not be in our tree yet. This was broken in
commit e7bd73f2b0.
These turned out to break existing ui files, concretely
GWeatherLocationEntry was no longer guessed correctly.
Update the testcases to reflect this, and add a testcase
for GWeather.
"Hey I know, let's do an easter egg!"
"What kind of easter egg?"
"We can nest lots of textviews!"
"Sounds cool!"
...
"But how does one see a textview inside a textview?"
"What do you mean?"
"Well, it just looks like black text on a white background."
"You mean it's the same as if we just duplicated the text?"
"Yeah!"
"Hrm, maybe we can put a frame around it."
"Sounds good. I'll stuff the textviews in a GtkFrame."
"What? Why? Let's use a GtkEventBox and override its background"
"Why is that a good idea when we have GtkFrame?"
"Because I said so!"
"Okay."
Overriding the background color for a color swatch is wrong. The color
is not the background, it's the foreground, so it should be painted in
a draw signal handler.
