TMS export projection and extent

Great new feature of GM12 is the TMS export. However it seems like GM reprojects our image to a different projection (Google 900913 ?? ) . Is it possible somehow to generate tiles for a projection and extent of choice?

Thanks,

    If you want to put your tiles over any of the web map ones, they all use the mercator/sphere projection or whatever its called. So most tiled products use that projection.

    That is correct, the OSM and TMS tile schemes are defined relative to the "Web Mercator" projection (aka Google 900913, etc.). If they were tiled to a different projection then they wouldn't fit those standards anymore.

    It would be nice to being able to keep current projection for tiling as an option since not every one likes the 900913 projection. Here in Iceland (and other far north or south countries) the projection makes everything look very distorted.

    We plan on adding support for more custom tiling schemes in the future, they just wouldn't match up with the OSM/TMS standards anymore.
