reads a .bmp and slices tiles 19 across and 8 down
then writes to matrix

map editor http://tilemap.co.uk/zipfiles/mapwin1422.zip
characters http://reinerstileset.4players.de/humansE.html

take map tiles and put into matrix
dbCreateAnimatedSprite reads tiles in top-down left to right
dbSetMatrixTile co-ords are down-up left to right with first co-ords at 0,0
