[hackers] [st][PATCH] Set minimum window size to avoid crash when resizing out of bounds

[Michael Buch]

The terminal window is created without lower/upper bounds
for window width/height. On resizing the terminal to a size
of 1x1 or below we crash. This patch sets the minimum
window height and width to prevent resizing past this size
and handling the scenario similar to other terminals.
