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.
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).

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.
- gtk_style_context_get_background_color()
- gtk_style_context_get_border_color()
Those functions shouldn't be used anymore, because they don't represent
anything from the CSS styling we support. The background color often
isn't used due to background images and there are actually 4 different
border colors (1 for each side) - if there isn't also a border image in
use.
Instead of drawing a gradient in the background color, draw a CSS box.
And change the theme so instead of setting just a background color it
draws a gradient.
The resulting visuals are the same.
Instead of drawing text for selections and links manually, use the
gtk_render_background() and gtk_render_layout() functions.
As a side effect, this allows shadows on selected text and links
and real backgrounds (like gradients or images), too.
I tried asking but nobody knew why it is necessary to set the background
color of the first cell. It seems with CSS styling this is completely
unnecessary.
This fixes shadows that are animated not updating the clip of the widget
they are drawn on. An example of this are the buttons in the CSS shadows
example in gtk-demo.
