[[ RefactorGraphics ]] Initial implementation of improved spread algorithm (uses distance transform, rather than dilation).
[[ RefactorGraphics ]] Moved spread code to separate file as it is licensed differently.
[[ RefactorGraphics ]] Added community license header to all source files.
[[ RefactorGraphics ]] Fixed error in distance calculation in y direction.
[[ RefactorGraphics ]] Updated all projects with new file.
Merge branch 'feature-improved_spread' into develop
