Fix DPI

[rsaxvc]

1st gen devices seem to use 404? 401? DPI. But some of our tools use 100 or 404.

I'm noticing I'm having to scale 400% on my Expression 2.34, and it doesn't matter if have the document is in inches or mm.

Which tool were you using to process your document?

I was using InkScape to design my stuff then doing the CLI app. I've since moved on, and swapped to the FreeExpression Firmware (https://github.com/ellisgl/FreeExpression), so I won't be able to help anymore.
