Texture support

[jfbourdon]

The viewer is clearly oriented toward 3D printing so texture (in OBJ or glTF format #4) is rater irrelevant, but texture support could be useful to some (well... me). If this is too much out of the scope of your viewer, I'll then need to learn javascript which wouldn't be a bad idea...

I second this request for texture support. I measure scanned objects a lot and having the texture enabled allows me to select features which are only visible in this mode.
