A library to copy a raster into memory. This is esp. useful for raster types such as TileTiffRaster which seem not to support repeated reading

This is a library for "punching through" a raster - e.g. in the centre point of a grid cell - to see whether that point is located within an underlying shape or not. So far it's only working with shape files.

A code block in the cliplib was surrounded with "try" and "finally" to make sure the raster is always reset whatever happens.
