A modified/commented version of the multithread gdal2tiles from http://trac.osgeo.org/gdal/ticket/4379
I know almost nothing about python currently so surely my additional code will be terrible
Goals:
- Restore the auto zoom level determination ability in the multithread version (done, thoough very badly)
- Better comment the code to see how the current process works
- Optimize the process
- Improve the quality of output graphics
- Create a client/server version to distribute work amongst machines
