* remove semicolon after namespaceAlexander Sulfrian2014-05-046-6/+6
| | | | | Class definitions have to end with a semicolon but not namespaces. So remove this everywhere.
* utils/colors: move colors into subdir, add hsvAlexander Sulfrian2014-04-086-0/+559
All color classes are now in an own subdirectory with a short name. The new class HsvColor represents the Hue/Saturation/Value color model and comes with conversion functions to and from rgb colors (currently integer arithmetic without optimization for higher presicion).
