Is it just me, or is the result/documentation for gdaldem hillshade off
by 90 degrees?
While the docs state "azimuth of the light, in degrees. 0 if it comes
from the top of the raster, 90 from the east, ..." (so: clockwise from
north), I find that a sun azimuth of 0 degrees is west, 90 is south, 180
is east and 270 is north (counter-clockwise from west)...
