\class Qt3D::QAbstractTextureImage
\since 5.5
\brief Encapsulates the necessary information to create an OpenGL texture image.
Qt3D::QAbstractTextureImage should be used as the mean of providing image data to a
Qt3D::QAbstractTextureProvider. It contains the necessary informations: 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. Qt3D::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.
