[Interest] [qt3d] Loading textures from a custom file format

I am trying to understand how I have to use QAbstractTexture and
QAbstractTextureImage to load textures from our custom format.
Our format is pretty simple and consist in a compressed file that contains
an header with all necessary informations :
- texture size
- precise texture format (PVRTCI_4bpp_RGBA, ETC1,...)
- number of mipmaps
And it's naturally followed by the pixels buffer.
If I understand correctly how it works the best way to manage it is to
create a Texture class that will load the file and instantiate TextureImage
corresponding to the number of mipmaps level I have.
Am I right?
