QTexture refactoring

Target is now set in the ctor from C++. On the QML side, there's a QTexture
subclass for each target.

WrapMode on s, t, r for texture, accessible as a grouped property in QML.

Note: I left out the static fromImage as I didn't really understand their
purpose. Please let me know what I'm missing.
