In the following file, "currently held tile" is understood to mean
the tile you have in hand, OR a random tile from the current random selection,
if Random mode is on.

Scene Size    Change the dimensions of your scene.  You can change the size
              by clicking the arrow keys or typing the value in the number
              box.  Pressing the right mouse button on the arrows will
              increase or decrease by tens.  Changes won't take affect
              unless you click the Resize button.  If the desired size
              is too big for your memory then Scene Editor simply aborts.
              You will not lose your current scene or brush.
Tile Size     Alternate the tile sizes between 16 x 16 pixel tiles and
              32 x 32 pixel tiles.  16 x 16 pixel tiles allow more tiles on
              screen but are take more time for the scene commands to draw.
              32x32 tiles take less time to draw, but less fit on screen.
              Changes won't take affect unless you click the Resize button.
              The scene and icon bank will not be cleared, so if your
              icons are not the right size, you may get lots of garbage 
              on screen and on the tile screen.  It is strongly suggested
              you load icons of the right size!
Automaze Mode This feature allows you to draw mazes "on the fly."

              mode between Walls and Walkways.  
Maze Generator   Access the Maze Generator.  Scene Editor asks for TL & BR.
              (top left, bottom right) Esc cancels.

              that will not be affected by drawing operations.

              for RANDOM mode.
