wresize - resize a curses window
int wresize(WINDOW *win, int lines, int columns);
The wresize function reallocates storage for an ncurses window to
adjust its dimensions to the specified values. If either dimension is
larger than the current values, the window's data is filled with blanks
that have the current background rendition (as set by wbkgndset) merged
The function returns the integer ERR upon failure and OK on success.
It will fail if either of the dimensions less than or equal to zero, or
if an error occurs while (re)allocating memory for the window.
The only restriction placed on the dimensions is that they be greater
than zero. The dimensions are not compared to curses screen dimensions
to simplify the logic of resizeterm. The caller must ensure that the
window's dimensions fit within the actual screen dimensions.
