Grid Redstone.png  Function window.reposition
A function available to window-based terminal objects created via the window API, which moves and / or resizes the window in concern.

If visible, the window will be automatically re-rendered, however the parent terminal object won't be (meaning "ghost" images of the window's previous shape / location may be left behind unless you manually clear them).

If shrinking a window will result in some of its contents being cropped from view, then that content will be removed from the window's buffer and will not be restored if you later re-enlarge it. If a new width / height is not specified then the window will retain its previous dimensions.

Stretches and bounces a small window filled with white around the display until terminated (Ctrl + T).
local xSize, ySize = term.getSize()
local xPos, yPos, xLen, yLen = math.random(xSize-5), math.random(ySize-5), math.random(5), math.random(5)
local xDir, yDir, xLenDir, yLenDir = 1, 1, 1, 1

local smallWindow = window.create(term.current(), xPos, yPos, xLen, yLen)

while true do
	xPos = xPos + xDir
	yPos = yPos + yDir
	xLen = xLen + xLenDir
	yLen = yLen + yLenDir
	smallWindow.reposition(xPos, yPos, xLen, yLen)
	if xPos <= 1 then xDir = 1 end
	if xPos + xLen >= xSize + 1 then xDir = -1 end
	if yPos <= 1 then yDir = 1 end
	if yPos + yLen >= ySize + 1 then yDir = -1 end
	if xLen <= 1 then xLenDir = 1 end
	if xLen >= 5 then xLenDir = -1 end
	if yLen <= 1 then yLenDir = 1 end
	if yLen >= 5 then yLenDir = -1 end
