Detailed Description

VertexStreamAttribute is used to specify the vertex attribute for drawing, which is correspondent to glVertexAttribPointer(GLuint indx, GLint size, GLenum type, GLboolean normalized, GLsizei stride, const GLvoid* ptr).

_semantic -> index _size -> size _type -> type _normalize -> normalized _offset is used to compute the start offset in a interleaved array, take a V3F_C4B_T2F array, offset of vertex will be 0, offset of color would be 0 + sizeof(float) * 3 = 12, offset of texture coord would be 12 + sizeof(char) * 4 = 16.
