CC3Texture asCCTexture2D adds spawned CCTexture2D instance to CCTextureCache.

CC3Texture asCCTexture2D adds spawned CCTexture2D instance to CCTextureCache.
CC3Texture hands GL state mgmt to CC3UnmanagedTexture2D that it spawned when
it is deallocated. Rename CC3VertexTextureCoordinates alignWithTextureMapSize:
and alignWithInvertedTextureMapSize: to alignWithTextureCoverage: and
alignWithInvertedTextureCoverage:
CC3Backgrounder uses serial queue instead of concurrent queue.
Add bone quaternion, translation & scale shader program semantics.

Add bone quaternion, translation & scale shader program semantics.
Extract translations from matrices. CC3Node globalLocation is extracted
from globalTransformMatrix. Simplify CC3Matrix4x3 extraction functions.
Add CC3DataArray class to support managing and accessing arrays of structures.
Cache bone matrices in CC3NodeDrawingVisitor for retrieval by shader semantics.
Add experimental CC3TexturableRigidBones.vsh shader.
CC3Camera FOV management enhancements.

Add CC3Camera fieldOfViewOrientation & fieldOfViewAspectOrientation to make
FOV management consistent and independent of display orientation. Default
CC3Camera to use diagonal FOV. Default CC3PODCamera to use horizontal FOV.
CC3Scene sets itself as parent of backdrop node when it is set.

CC3Scene sets itself as parent of backdrop node when it is set so drawing
visitor has access to view surface when first rendering backdrop.
cocos3d CCTextureCache extension working with cocos2d 1.0.1, 1.1, 2.0 & 2.1.
