Big skeletal animation update
Added MeshInfos demo Added MD5Mesh/MD5Anim loader support Added Node class Fixed ResourceParams not being exported Added support for skeletal animation (Animation/Mesh/Joint/SkeletalMesh/Skeleton) Meshes are now only stored with VertexStruct_XYZ_Normal_UV_Tangent type Moved Sequence declaration to Sequence.hpp -Animation: Renamed Create to Create[Keyframe|Skeletal] -AxisAlignedBox: Added Contains method Added GetCorner method Added GetCube method Added Transform method -Cube/Rect: Added GetPosition method Added GetSize method (Almost) Fixed ExtendTo method Fixed GetCenter method -File: Added GetDirectory static function Added GetPath method Renamed GetDirectoryPath method to GetDirectory -Math module: Fixed constructor/methods taking a non-const array GetNormal/Normalize methods now takes an optionnal integer pointer (returning length) Made all classes default constructor trivial Inverse, MakeIdentity, MakeZero, Normalize, Set methods now returns reference to object -Matrix4: Modified methods to avoid copies Removed COW (Too much overhead) Removed Concatenate[Affine] static function -Mesh: Renamed Create to Create[Keyframe|Skeletal|Static] Renamed Skin to Material -MeshParams: No longer takes declaration argument Renamed loadAnimations to animated Storage default to BufferStorage_Hardware if supported and BufferStorage_Software otherwise -OpenGL: Added glGetBooleanv function Added glIsEnabled function -Quaternion: Added ComputeW method Added Conjugate method -Renderer: Added IsEnabled static function Fixed GetLineWidth function not being static Removed SetVertexDeclaration -RenderWindow: Made CopyTo[Image|Texture] method constant -Resource Fixed RemoveResourceListener crash -ResourceLoader: Loaders are now used in a LIFO context -Stream: Renamed GetLine method to ReadLine -String: Fixed Simplified -Utility module Added configuration define for strict resource parsing -VertexBuffer Now takes a VertexDeclaration pointer -VertexDeclaration No longer throw an error when getting a non-existing element Former-commit-id: f7358c1231d6af48b799d2f24f077a001e16785b
