comment Can I avoid runtime raster interpolation by creating an image pyramid to match the zoom scales?
This is what I ended up doing, it was just a matter of figuring out how to map between scales and image resolution

comment Google Maps zoom level --> ratio…?
The scales were chosen so that they can be evenly divided by raster tiles that are in base 2, (e.g. 128, 512...). Bing does it similarly msdn.microsoft.com/en-us/library/bb259689.aspx

comment How do you change the prime meridian of a map?
I am working on a data translation script to do this (cut the shapes and rotate meridian). Unfortunately we use proprietary tools (FME) so I cannot post a general solution.

You were right, the shapes are getting "stretched" across the map which was causing the distortion. The shapes need to be "cut" before changing the meridian.

What does a fix geometry involve? Export it to what format?
