Grid
This is a grid pattern representing the whole of the monitor screen. The grid
makes it easy to set the position of an image in two-dimensional coordinates.
Shrinking the graphics display
You can shrink the graphics display so that you can see beyond the range
displayed on the normal monitor screen. This makes it possible to visually set
the location of images in a larger space. The range displayed on a normal
monitor screen is indicated by a frame.
