resize Subroutine

private subroutine resize(self, width, height, pixel_ratio)

The host window was resized (framebuffer pixels), and pixel_ratio: its framebuffer pixels per window unit (Qt's devicePixelRatio), if it may have changed (the window moved to a screen of another scale, or the display's scaling changed: sizes in window units, such as line widths, markers and labels, are scaled by it). Once the scene is shown, a frame of the new size is rendered at once (call this from the host's resize event), so that the window isn't shown stretched or blank while it is resized.
