Re-used existing route and moved tinymce help to its own different
route. Added test to cover.
Added new external-content block to support in editor UI.
Adds dynamic and fixed (out of DOM order) positioning with location
adjustment depending on space.
Also adds smarter hiding to prevent disappearing when mouse leaves but
within the same space as the toggle.
Changes the name of our spacing variables due to the prefixing -/_
meaning private in the use of new "use" rather than include.
All now modular too, so all variables/mixins are accessed via their
package.
Also renamed variables file to vars for simpler/cleaner access/writing.
eg. '$-m' is now 'vars.$m'
- Updated toolbar to match existing editor, including dynamic RTL/LTR
controls.
- Updated text node handling to not include spans and extra classes when
not needed. Added & update tests to cover.
- Improved node resizer positioning to be more accurate
- Fixed drop handling not running within editor margin space
- Made media dom update smarter to reduce reloads
- Fixed media alignment, broken due to added wrapper
Changed from using a decorator to using a helper that watches for image
selections to then display a resize helper.
Also changes resizer to use a ghost and apply changes on end instead of
continuosly during resize.
Also added smarter above/below positioning to respond if toolbar would
be off the bottom of the editor, and added hide/show when they'd go
outside editor scroll bounds.
Added new options that sits on the context, for things needed but not
for the core editor, which are defined out of the editor (drawio URL,
error message text, pageId etc...)
