I'm suggesting to implement an ability for users to set texture source from C++ side using QByteArray.
I propose to implement this because the only way to set the texture: first save the texture to the hard disk, and then set the material path to the texture - but it is too long and useless operation. 

A picture in the QByteArray format comes to our side from other module / library. And we want to set this picture as a texture on a rectangle in a 3D presentation. And we need a method (for example, Q3DSPresentation::setTexture (const QString& materialPath, const QByteArray &data)) in the Q3DSPresentation class.
