[edit] Surfaces

Surfaces is a new feature that was added in Game Maker 6.1, it allows the user to use the normal draw functions to draw on a canvas, or a “surface” once, and then, it can be saved to a file, drawn on the screen, go through some manipulations and rotations, or get copied to another surface. You draw a line to the screen, then the line is saved on the surface, and the surface is drawn at the end of each step, which means that even if you draw thousands of lines on the surface, then draw the surface on the screen, the game will still run fast, as the surface is drawn all at once, not each line separately.
