- TMT versie in Nederlandse taal (functionality unchanged)
- added LINE visvars: texture, form, rotation -- uses polygons of BUFFERed lines (expects a file named %DATA_URL%_buffer).
- added POINT visvars: colour, form, texture,
orientation, value and size- for orientation used a workaround from #jwoLondon, in expectation of angle encoding slated for VL 4.1.

%TEMPLATE_ITEM%
instead of simple 'TEMPLATE' search & replace - total rewrite offillTemplate(items)
andcreateMap(guiState)
