Detailed Description

data holder describing OpenGL texture objects in addition to its unique texID.

Please note that querying glTexImage2D(GL_PROXY_TEXTURE_2D,... may be more reliable See http://www.opengl.org/resources/faq/technical/texture.htm

Bug:: TODO copy constructor that duplicates the GL pixel data required for std::vector.resize() (major bug, do not resize with std::vector for now!)
