Get the dimensions of the terminal window in pixels
term_dim()An integer vector with the width and height of the terminal in pixels
(x_pixels and y_pixels) and the number of text columns and rows
in the terminal window (columns and rows).
These values can be zero when the terminal does not support querying the size. Some terminals only support querying the number of columns and rows. Under windows the return value will always be zero as querying the size depends on POSIX support.
term_width and term_height for only obtaining
the width and height in pixels respectively.
