- Removed ImageMagick as a dependency.
- VideoStream window now closes as expected when endStream() is called
- Displaying a greyscale image now displays it correctly (before it was pink)
- Added clone() method to the Picture objects to create a copy of a picture
- Added more error reporting for improper use of the library
- Added myro-cpp-config script to get compiling information, which can be used instead of pkg-config (but we do not remove pkg-config support)
