Bulk action marks printed + schwag, but as print is automated and
happens after checkin is flagged, we should only set checkin and schwag
and print will happen.
Don't block submition, but give the user a red bar.
Also a link to overview.
Esp if it is 5+ sec to load, we don't need it 90%+ the time, don't page
through it in the scan print workflow.
Support so print can print only important text.
SVG modified to use display:inline/none based on overlay True/False and
a symlink to make it easy to change to a completely seperate svg if that
is not optimal.
SVG added layers to split text and graphic so graphics can be easily
hidden and printed.
Closes: #38
* Add a note about the creation date of boarding pass
* Add a link to ticket review page
* Try to handle some of the expected errors in the boarding pass
sending process
* don't just 502, try to handle the error and move on.
- The schedule grid page is ridculously database-query heavy and hence
terribly lacking in perfmantitude.
- Caching can help with this, but the caching implemention at present
is not user-aware. If one user looks at the page, they'll get a
"YOU" in all the places they're chair and something else everywhere
else - and then everyone will see that for the next 600 seconds,
then YOU will become someone else
- to avoid this, remove the request.user-specific bit of the template
- Use the first template in the system
- If there's no template, use /tickets/review as it at least gives
- people an overview of what they've paid for and warns them of
missing categories
* The qrcode contains no information that isn't in the URL you used to
access the code, so information is being leaked
* Allowing unauthenicated access lets people see the image in their
mail client
Not ideal. Let's revert this later and think of something better next
year - perhaps spending some more time researching best practices on
images in email..
* Switch to showing the PNG version by default, as this reflects what
will actually be rendered and sent to the printer
* Include the greyscale filter
* Include the twemoji font we'll use for rendering the badges
