It seems that the cheapo installer that comes with VS2010 doesn't include the redistributables. I should probably include a note. I should probably get also a real installer program some day, but that sounds hard. The UI in this version uses less custom components and more straight VS2010 things, so it might work better. The OpenGL preview is still the same custom code, though, so it may still have the same problems there.

The V2 shader was what I arrived at by being lazy. The default should look suspiciously similar to certain shading styles on maps hereabouts.
