SDL dies, SFML lives!
first step: render empty window using SFML
expand readme
start with drawing map
drawing tiles, cell moved to separate class
got rid of sf::Image
adjustments
succesfully drawing 4PL_Mountains.ini
converted terrain type ints to enum
cleaned up
sf::View allows scrolling around with arrow keys
CMake should now find SFML automatically.
tile index set correctly
add working makefile.osx file (for now I don't have cmake working, will
work on that)
make cmake work for mac os x
add findSFML.cmake so it detects sfml on mac os x
ignore cmake related files
 no need to use makefile.xxx anymore, just use cmake
rename dune2 to d2tm
change readme to reflect changes to cmake
