0.6.0

• Changed the way components are defined and accessed (through Entity.components instead of Entity.getComponentsByType etc).
• Optimize entity/component traversal
• Add GL.setVertexLayout as the de facto way to assign vertex attributes
• Introduced VertexLayoutCache internally to share vertex layout objects between instances, possibly reducing amount of render state changes
• Added MeshBatch to allow rendering multiple instances with a single draw call
• GL: Do not require explicit enableVertexArray calls
• Create predefined hx_lodRange vec2 shader uniform, containing MeshInstance’s lodRangeStart and lodRangeEnd
• Terrain now extends Entity instead of Component
• Terrain: change constructor signature and the way the terrain LOD geometry is constructed
• Create predefined hx_heightMap, hx_heightMapSize, hx_worldSize passed to material in Terrain.
• Create abstract Texture base class for Texture2D and TextureCube
• Added QuadPartitioning
• BasicMaterial:
  • Added translucency and translucencyMap
  • Added billboardMode
• Added Impostor util to generate basic impostors from meshes
• Added LightingModel.Lambert for diffuse-only lighting.
• Updated terrain example with trees and grass
• Created ImpostorPrimitive
• Added META.TIME property and hx_time shader uniform
• TextureUtils.getData: Do not allow reading back from float textures except to encode greyscale data to rgba (due to Safari not supporting float readbacks)
• VarianceShadowFilter: Change default parameters to use full float and reduce bleeding
• Change sponza example model to gltf
• Renderer.DebugMode: Replace NORMALS_DEPTH debug mode with separate NORMALS and DEPTH

BugFixes:

• HCM: Fix progress notifications when loading mipchains
• Touch: Clear pinch value on touch up
• Raycaster: Prevent some false intersections.
• RenderCollector: Fix render order hint calculations to work as distance.
• Raycaster: Correctly test hierarchy visibility
• Prevent infinite bounds from affecting shadow bounds
• Shader: Do not insert derivatives extension in shaders when using WebGL 2 contexts
• DDS: Fix all half_float uploads if not supported (Safari)
• Fix ambient occlusion shaders when using WebGL 2 contexts
