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
In the narrow view, lots of details that aren't in the normal view
appear to compensate for not having clear row/column headers any more.
However, all the detail can look very same-same; this tweak makes rooms and end times more distinct.
Session chair info is made always italic, and a label is added to make
it clear that this person is not the speaker.
