- This is a follow-up to d0c205c1cc6a2ae49935c92bfd52911b9a0d43f7;
I really don't know why static constexpr const elements that are
not referenced by address need to be defined separately.
- QImage needs Qt5::Gui, so this isn't a guiless-test; it can use
the offscreen QPA, though.
- Check that the images are all the same size
- Debugging / check code removed from timezonewidget
- all the TZ location information now lives in the Calamares
locale service and the TZ list
- replace the Location class that was local to the timezone
widget by the TZZone class
- chase a bunch of small API changes that this needs
- Used in only one place, move to .cpp
- Drop useless scaling all the images *are* that size already
- Add debugging check that the images match expected size
- Fudge the numbers in the North, to improve location
of the pins and lines of latitude.
- Inuvik, Yellowknife, Cambridge Bay, Resolute look ok
- Thule, Scoresbysund look ok; Danmarkshavn a pixel or so too far North
- Reykjavik is a bit too far North
- Longyearbyen is a bit too far North
Since these places are off by one or two pixels, this becomes
invisible when a large pin + text label is placed on it.
The scaling on the map was a little off; the degrees of latitude
are a little wider there than around the equator and Europe.
- Johannesburg is in the right spot
- Hobart is no longer a suburb of Melbourne
- Punta Arenas is in Chile
Replace pin and text label with just a dot (to pinpoint where
locations are) and draw latitude lines on the globe when
DEbUG_TIMEZONE is set at compile time. Since there's probably
still timezone-related bugs (in particular in the images that
map points on the globe to timezones), leave this in the codebase.
In the timezone widget, locations in the far north -- Inuvik,
Thule, Longyearbyen -- were displayed too far south, because the
map location calculation assumes a linear gradient, which places
90 degrees north at about 70 degrees. Change calculation to
pretend the world is flat south of 62 degrees north, and then
'bend' the remaining 28 degrees of latitude to the top of the
image. This puts most places in the right spot, although Yellowknife
is now on the south shore of Great Slave.
Fort Nelson should be north of Dawson Creek, too -- the math still
needs a little work.
While here, put Antarctica in the south, otherwise Rothera keeps
showing up in Greenland.
