*resize* shrink|grow width|height [<amount> [px|ppt]]

percentage points. If the units are omitted, floating containers are resized
in px and tiled containers by ppt. _amount_ will default to 10 if omitted.
*resize set* <width> [px] <height> [px]
Sets the width and height of the currently focused container to _width_
pixels and _height_ pixels. The [px] parameters are optional and have no
effect. This command only accepts a size in pixels. Width and height may be
specified in either order.
*resize set* <width> [px|ppt] <height> [px|ppt]
Sets the width and height of the currently focused container to _width_ and
_height_, specified in pixels or percentage points. If the units are
omitted, floating containers are resized in px and tiled containers by ppt.
If _width_ or _height_ is 0, no resize is done on that axis.

Shows a window from the scratchpad. Repeatedly using this command will
