d70cd72fbd Don't automatically try to preserve polygon elevations, but instead provide 
a method() to inherit elevations from another polygon.  This gives the calling
layer much more control over preserving or not preserving elevations.

c5ab6678f2 Added support for including height information in the intermediate polygon 
format.  The big trick was that the polygon clipper is completely 2d.  So
I needed to add code to preserve the elevations in the clipped output and
fill in plausible elevations for any new points created as a result of the
clipping.

9c85f16b5f Working towards the ability to specify elevations for a polygon in it's 
intermediate mode.  The goal then is that these elevations would be
preserved throughout the tile construction process and the surrounding
geometry would fill in without gaps.  This has potential applications for
airports and runways of course as well as roads, rivers, streams, railroads,
or any other object where we might want to control the final elevation in
advance.

7c3f6dd15d Dohhh, I knew I would screw it up the first time. But no, I doubly screwed 
it up.  Read the rows from bottom to top rather than top to bottom and
flipped row/col ...

4bb5decbcb A simple perl::GD script to convert .hgt to a .png for visualization purposes. 
The explicite draw each pixel method is inefficient, but used anyway to make
it utterly clear what the data order is in the original .hgt file.

15ba15538b Output file is written with a ".arr" (Array) extension since it's no longer 
in .dem format.  The .arr format is a much simpler (and a bit less flexible)
specifically for use as an intermediate format when building scenery.  Any
number of various raw terrain formats could be translated into the common
.arr format which then greatly simplifies life for the build tiles util.

2b660877a3 Don't generate a DEM tile when all elevations are zero. This should

fbb232280e Frederic Bouvier: 
Well, I found a bug in VpfTile that prevents the function getTileSubdir
to return the correct value.

In that case getTileSubdir was returning the content of a local
variable (subdir) that is destroyed before used outside. Usually,
it generates a segfault with MSVC but here, the returned string
was "". The patch returns the value of the string and tgpvf is
going well so far.
