Imagemagick does not generate svg images very well, but it can convert
them to png quite well.
For browsers that don't yet support displaying svg, this also provides a
workaround; just scale the svg down to get a png. But the workaround is
partial, since scaling the image larger, or leaving it the same size will
cause the original svg to be displayed. Since browsers are actively
improving svg support, this is good enough for me.
Firefox sent an accept header for application/xml, not application/json,
and also weakened the priority to 0.8. So that stuff is not to be trusted;
instead I found a better way: When an ajax upload is *not* being made,
the Upload Attachment button will be used, so enable ajax if an upload
is being made without that button having been used.
Also, testing with firefox revealed it refused to process a response that
was type application/json, and checking the demo page for the jquery file
upload plugin, it actually returns the json with type text/html. Ugh.
Followed suite.
Now tested with: chromium, chromium (w/o js), firefox, firefox (w/o js),
and w3m.
Needed for attachment to return json when requested.
I think some browsers send Accept: * , so I made sure to check that json
was explicitly listed as to be accepted, as well as having a high
priority.
Left out confirmation of removal for held attachments because
a) they're not in the wiki yet, so confirmation is a bit unnecessary
b) it would be hard
c) eases later integration of jquery file upload interface
Also changed where attachments of index are held (to match where they're
stored in the srcdir).
Note that the attachment formbuilder hook was made to run last, so that
the list of attachments is not generated before removal, in the fast path
w/o confirm.
Note that it's possible for an attachment in the holding area to be older
than an attachemnt in the wiki with the same name. I intentionally
show the one in the holding area in this (unlikely) case, since saving the
page will overwrite the wiki's file with the held attachment. It does not
seem worth the bother of doing something more intelligent, since in this
case two people have basically conflicted with one-another.. and both
attachment contents will be stored in revision control in case it needs to
be sorted out.
I had to remove the hyperlink for attachments in the holding area, since
they're not yet live on the web. This could be annoying/confusing. Added
a moseover notice instead.
This makes uploading a lot of attachments somewhat faster, because
the user does not need to wait for a long website refresh after each
upload. Still probably somewhat slow, since ikiwiki has to run for each
upload.
More importantly, this opens the door for integration of things like
the jquery file upload interface, which allow drag-n-drop and multiple
file uploads to be queued and then ran.
It uses rcs_commit_staged, which leaves out tla and mercurual which lack
that, but since rename, remove, autoindex, etc also use that, I think it's
fine for attachments to also depend on it.
The attachment list is currently broken; it does not look in the holding
area yet, and its links to the attached files won't work since they're not
yet in the wiki. previewing is also currently broken.

Two problems fixed:
1. Files are written with a .ikiwiki-new suffix, which has to be taken into
account.
2. Need to count length of bytes, not of unicode characters.
Arguably, the real bug is in the interface to add_autofile, but since
that does take a filename, not a page name, it cannot really do case
handling on its own. The only other users of add_autofile in ikiwiki proper
is autoindex, and it always uses one case. Other third party plugins might
also need to add similar workarounds though.
