Utils

Classes :
- Dtk_Camera:
  - Dtk_Camera documentation has been deeply rewritten.
  - The Dtk_Camera::Focus() method has been deprecated and is now superseed by Dtk_Camera::GetFocusDistance().
  - Dtk_Camera::TargetVector() method has been deprecated and is now superseed by Dtk_Camera::TargetPoint().
  - Dtk_Camera::ZoomFactor() method has been deprecated and splitted and is now superseed by Dtk_Camera::ProcessXZoomFactor() and Dtk_Camera::ProcessYZoomFactor().
  - Dtk_Camera::Angle() method has been deprecated and is now superseed by Dtk_Camera::ProcessXSemiAngle() and Dtk_Camera::ProcessYSemiAngle().
  - A new Dtk_Camera constructor has been written taking the relevant values - origin and target points, upvector, semi-width, semi-height - and superseeds the previous one.
