- it'll help to be able to move popups on screen to let the user read the text
- popups won't inherit some properties from their parent:
- the popup can be misrendered if for example the parent has a clip-path property.
- add an outline to the popup when the parent is focused.
- hide a popup when it's clicked.
While this slightly reduces duplication in the CSS rules, some of the auto-formatting done by Prettier is perhaps not great. (Given the overall advantage of using Prettier, we'll probably have to simply accept this.)
An annotation doesn't have to be in the text flow, hence it's likely a bad idea
to insert its text in the text layer. But the text must be visible from a screen
reader point of view so it must somewhere in the DOM.
So with this patch, the text from a FreeText annotation is extracted and added in
a div in its HTML counterpart, and with the patch #15237 the text should be visible
and positioned relatively to the text flow.
- each annotation has its coordinates/dimensions expressed in percentage,
hence it's correctly positioned whatever the scale factor is;
- the font sizes are expressed in percentage too and the main font size
is scaled thanks a css var (--scale-factor);
- the rotation is now applied on the div annotationLayer;
- this patch improve the rendering of some strings where the glyph spacing
was not correct (it's a Firefox bug);
- it helps to simplify the code and it should slightly improve the update of
page (on zoom or rotation).
Note that these changes were done automatically, using `gulp lint --fix`.
With this rule, we'll thus enforce a *consistent* formatting of zero-lengths in our CSS files.

This includes the information in the core and display layers. The
date parsing logic from the document properties is rewritten according
to the specification and now includes unit tests.
Moreover, missing unit tests for the color of a popup annotation have
been added.
Finally the styling of the popup is changed slightly to make the text a
bit smaller (it's currently quite large in comparison to other viewers)
and to make the drop shadow a bit more subtle. The former is done to be
able to easily include the modification date in the popup similar to how
other viewers do this.
In `rasterizeAnnotationLayer` we load the source CSS files directly, so
these are not processed by Autoprefixer. Since the prefixed rules have
now been removed from the source CSS files, we must manually provide one
prefixed rule that Chrome needs in the overrides CSS file for checkbox
and radio button rendering to work in the reference tests.
reference tests
This patch allows us to use the common styles as used by the viewer as a
baseline for the annotation layer reference tests. They are extended
with a small set of overrides to ensure that all elements are visible
during the test.
The overrides file now only contains the absolutely necessary rules to
make all elements visible and is therefore no longer an almost verbatim
copy of the common styles.
