Box2D-2.4.1-bp152.4.6.1

- Update to version 2.4.1.
  * API Changes
  * Extended distance joint to have a minimum and maximum limit.
  * Removed rope joint. Use the distance joint instead.
  * B2_USER_SETTINGS and b2_user_settings.h can control user
    data, length units, and maximum polygon vertices.
  * Default user data is now uintptr_t instead of void*
  * b2FixtureDef::restitutionThreshold lets you set the
    restitution velocity threshold per fixture.
  * BREAKING Changes
  * BREAKING: distance joint 0 stiffness now means the spring is
    turned off rather than making the joint rigid.
  * BREAKING: distance joint minimum and maximum must be set
    correctly to get old behavior.
  * Infrastructure
  * Library installation function available in CMake.
  * Shared library (DLL) option available.
  * Bug fixes
- Updates since 2.3.1
  * Infrastructure
  * Documentation in Doxygen format
  * Unit test support
  * Continuous integration testing using Travis CI
  * Limited use of C++11 (nullptr and override)
  * Collision
  * Chain and edge shape must now be one-sided to eliminate ghost
    collisions
  * Broad-phase optimizations
  * Added b2ShapeCast for linear shape casting
  * Dynamics
  * Joint limits are now predictive and not stateful
  * Experimental 2D cloth (rope)
  * b2Body::SetActive -> b2Body::SetEnabled
  * Better support for running multiple worlds
  * Handle zero density better
  * The body behaves like a static body
  * The body is drawn with a red color
  * Added translation limit to wheel joint
  * World dump now writes to box2d_dump.inl
  * Static bodies are never awake
  * All joints with spring-dampers now use stiffness and damping
  * Added utility functions to convert frequency and damping
    ratio to stiffness and damping
- Remove Box2D-fix-version-2.3.1.patch, fixed.
- Change package name from Box2D to box2d.

- Fix the source URL

- Replace strange buildroot definition

- RPM group correction

- Fixed Factory review (License.txt is not packaged).
- Minor spec clean-up (may fix SLE build).
- Cmake release with debug info build type.

- Fixed tar.gz by osc service localrun download_files

- Update to new upstream version 2.3.1:
  * Polygon creation now computes the convex hull.
  * The convex hull code will merge vertices closer than
  dm_linearSlop.
  * Vertices no longer need to be ordered.
  * New GUI
  * Various other bugfixes
