When creating a new view, wlc usually returns an initial geometry with
size 1x1. Setting those values as desired width/height causes a problem
for some windows (QT5) because they don't request a new geometry for
instance when made floating, so the floating window becomes 1x1.
To fix this problem we can just omit setting the desired width/height on
new_view and instead let the clients request a certain size if they feel
like it. e.i. gnome-calculator.
