\brief Encapsulates the necessary information to create an OpenGL texture image.
QAbstractTextureImage should be used as the means of providing image data to a
QAbstractTextureProvider. It contains the necessary information: mipmap
level, layer, cube face load at the proper place data into an OpenGL texture.
The actual data is provided through a QTextureDataFunctor that will be
executed by Aspect jobs in the backend. QAbstractTextureImage should be
subclassed to provide a functor and eventual additional properties needed by
the functor to load actual data.
\note: QAbstractTextureImage should never be shared. Expect crashes, undefined
behavior at best if this rule is not respected.
