Resizes the currently focused container or view by _amount_. _amount_ can be
specified as "n px" or "n ppt" or "n px or n ppt".
**resize** <shrink|grow> <width|height> [<amount>] [px|ppt]::
Resizes the currently focused container or view by _amount_. _amount_ is
optional: the default value is 10 (either px or ppt depending on the view
type). The [px|ppt] parameter is optional. _px_ specifies that _amount_ refers
to pixels; _ppt_ specifies that _amount_ refers to percentage points of the
current dimension. Floating views use px dimensions by default (but can use
ppt if specified); tiled views use ppt dimensions by default (but can use px
if specified).
**resize** <width|height> <amount>::
Sets the _width_ or _height_ of the currently focused container to _amount_.
_amount_ can be specified as "n px" or "n ppt" or "n px or n ppt".

Sets the width and height of the currently focused container to _width_ pixels
