# Revision History:
# 0.1.1 - make default import 12x12 bin (fast) to not consume too much memory
#         by default (TJS - 2010-12-07)
# 0.1.2 - included into svn under the tree:
#         trunk/py/scripts/addons/io_convert_image_to_mesh_img
#         may be moved out to contrib once the blender downloader works well
#         (TJS - 2010-12-14)

    ## This is also a bit ugly and maybe an anti-pattern. The problem is that

    ## less than 16 GB RAM and getting at specific features in a DTM at full res
    ## may prove beneficial. Someday most mortals will have 16GB RAM.
