Added Meshes and Animations (And many more)
Added NzTexture::IsMipmappingSupported Color::(FromTo)HSV now takes hue and saturation in degrees Fixed Context::EnsureContext Fixed COW thread-safety (String, Image, Matrix4) Fixed Quatenion<T>::operator*(const Vector3<T>&) Fixed ResourceLoader Fixed String::Resize with a size of 0 Fixed Texture mipmapping crash Fixed per-class thread-safety IndexBuffer and VertexBuffer are now resources It is now possible to use more than 8 texcoords per shader Moved all enumerations into separate files (Core/Enums.hpp, Utility/Enums.hpp, ..) Removed NzContextParameters::defaultWindow VertexDeclaration has been rewritten (New interface/COW)
