Resolve "Let the user set the exact pixel size of a given viewport"
requested to merge BTost/met.3d:26-let-the-user-set-the-exact-pixel-size-of-a-given-viewport into master
Closes #26 (closed)
User can now resize a scene view by selecting it and pressing alt+r or via the scene view's system property: interaction->resize . Met.3D then tries to resize the view by resizing the window so the other views can keep their size if possible.
