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 What ratio scales do Google Maps zoom levels correspond to?
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?

Is there any way to change the meridian and not cause this?
