The F3 key allows entering a name of a picture to edit.

The F4 key renames a picture.

The F5 key adds a dependent picture (see the below section).

The F6 key is used to set configuration. Currently, this only sets the
default picture sizes. If you specify zero, then it will use the user
configuration, otherwise it is saved with the puzzle set, and will be
used when adding new pictures. You can specify multiple sizes; it will
create it with variants of all of those sizes. You can also specify the
same numbers multiple times if you want multiple variants of that size.


=== Drawing ===

The following keyboard commands are available:

Esc
  Leave the drawing screen.

The DEP lumps are dependent pictures; each one references one or more IMG
lumps, and specifies how to modify them to produce the new picture (e.g.
by rotating, mirroring, changing colours, etc).

The WAV lumps are sound effects. Each is a RIFF WAVE file; it must be of
a type which can be loaded by SDL. (This is currently not used.)

The PICEDIT.CFG lump stores the configuration for the picture editor. It
can safely be deleted.


=== Class definition file ===

This file is a plain text file which defines the classes of objects which
are used in the game. See class.doc for details of its format.
