Markers are poorly scaled

[chaosphere2112]

Working on the gui, decided to try generating pngs of all of the marker types, and re-re-discovered that our marker scaling is just awful.

Here's a good "baseline" marker (circle) at size 100:

Most of the "normal" markers are roughly the same size.

Here's dot, the default, at the same size:

As you can see, dot is much larger than circle. Adding to the annoyance, we have plus and cross, which need to be scaled up to the maximum size (300) to be similarly sized to circle:

Cross	Plus

Then there's the WMO symbols, which are (mostly) close to the right size when they're at size 10 (one tenth of the "baseline" size):

w00	w01	w02

Except, up of course, for a few outliers:

w06	w07
w09	w17

(plus several more)

And there's the worst one, hurricane, at size 2:

We should look at normalizing the sizes of markers so they're all about the same for any given size.

👍 This is awful 😢 we should fix this. May be 3.0 or earlier
