Bug#1019416: Raising severity of remaining wxwidgets3.2 transition blockers

[Olly Betts <olly@survex.com>]

severity 1019833 serious
thanks

(I raised the severity of most of these yesterday, but missed packages
where an upload to experimental has closed the bug while it's not yet
fixed in unstable.)

Accounting for packages which are fixed in experimental or in git we're
now under 30 packages left to do, so raising the severity to "serious".

Justification: https://wiki.debian.org/Teams/ReleaseTeam/Transitions

Please start to investigate making this transition if you haven't already.
In most cases it's proving to be an easy update, but in minority of
cases where there are obstacles it's much better to find that out sooner
rather than later.

Cheers,
    Olly
