+Importers parse only open or synthetic formats. The supported terrain source
+boundary currently consists of the original OpenVistaPro `ovp-text` plain-text
+heightfield format, script-level PNG heightmaps, and open SRTM/HGT, ESRI ASCII
+Grid, and GeoTIFF inputs. These all normalize to the same internal terrain
