* Fix popup location for tables
This commit introduces the `popupAbsCoords` option to the $button widget
and implements an absolut coordinate format.
Coordinates for popups are stored in the format `(x,y,w,h)`. These
coordinates are relative to the offset parent of the element that
defines the popup.
This commits adds a second format `@(x,y,w,h)`. Coordinates specified in
this format a relative to the pages root element.
The `popupAbsCoords` option of the $button widget enables the use of
this coordinates.
* Unify the declaration of the RegEx for parsing the popup-position
The regular expression was declared in three locations with the same
content. This commit supplies a new function `parseCoordinates` in
`popup.js`. This function returns the parsed coordinates and understands
the classic/absolute coordinates.
This function is used in `reveal.js` and `action-popup.js` to parse the
coordinates.
* Add documentation for coordinate systems
* Consolidate creating coordinate strings
The Popup object now contains a `buildCoordinates` method that can be
used to build coordinate strings. It takes an "enum" for the coordinate-
system to use. This makes everything easily extensible and prevents the
use of magic values.
* Add tests for `parseCoordinates` and `buildCoordinates`
* Add `tv-popup-abs-coords` to `collectDOMVariables`
This will make the absolute coordinates available for the
`DraggableWidget` and the `EventCatcherWidget`.
* Add documentation for the `tv-popup-abs-coords`
... to the `DraggableWidget` and the `EventCatcherWidget`.
This just brings the documentation for these commands more inline with
other deprecations, plus offers a link to the recommended alternative
as well as the explanation for deprecation
* add default settings for styled inline SPANs
* change color names in palettes and vanilla-base
* change parser behaviour if custom class is used
* tc-inline-style will only be set if no other custom setting is appliead
* Add tests for inline-styles
* add one more test
* remove space after if
* allow global keyboard shortcuts to override all other shortcuts by providing a special field
* rework the global shortcuts taking priority
* replace bool option with options object in KeyboardManager's keydown handler
* update keyboard shortcut documentation to add information about the new priority setting
* add support for priority global keyboard shortcuts to code mirror
* update the feature's docs to point out it was/will be introduced in 5.2.4
* rollback unnecessary change
