Examples
Creates a new Transform object and uses it to position and rotate a rectangle around its center.
function love.load()
rectwidth = 100
rectheight = 100
-- arguments are: x, y, angle, scalex, scaley, offsetx, offsety
transform = love.math.newTransform(100, 100, math.pi/4, 1, 1, rectwidth / 2, rectheight / 2)
end
function love.draw()
love.graphics.applyTransform(transform)
love.graphics.rectangle("fill", 0, 0, rectwidth, rectheight)
end
