Improve brand image quality

Because the brand images are provided at such low quality, they look terrible when increased to any reasonable size.

I think the solution is to upscale them, blur them, and then use some equivalent to Photoshop's "Threshold" to decrease the fall-off distance of the edges. Then those can be converted to SVGs, too.

This (using GraphicsMagick) is promising:

gm convert -resize 250 -gravity center -extent 300x300 -blur 100x5 -threshold 50% -threshold 60%

That works well on every image except those that have fine details, like

and

I think I should just mogrify all of these images, then go through and re-do any with fine details, tweaking the settings a bit.

Here, I integrate potrace per this blog entry:

gm convert -resize 250 -gravity center -extent 300x300 -blur 100x5 -threshold 65% input.png pgm:- |mkbitmap -f 32 -t 0.4 - -o - |potrace --svg -o output.svg

That works pretty well.
