CLIPPING AND FOREGROUND
**********

This section covers how sprites interact with tiles in a level; clipping is given to sprites when
they are created and can be changed occasionally, say if they are shot. Clipping alteration is
pretty simple; it can take values between 0-2; and 'foreground behavior' controlls whether a sprite
appears in front of Keen or behind him and such. (Values between 0-3)

Sprites will pass through tiles if their clipping is set to 0, but will hit them if it is 2. If it is
1 then they will hit tiles, but will not be pushed out of them if they get 'inside' by accident. However
you will notice most sprites aren't given a clipping at all, this is because they use standard 'look
for walls' code and so don't actually need clipping as such. The forground behavior is either 0
(Go behind everything) 2 (Go in front of Keen and tiles) or 3 (Go in front of everything, including
foreground tiles.)

Foreground affects only sprite-tile interaction, a sprite that is spawned first will appear in front
of one spawned later, no matter what foreground property it has. (Sprites on the top left of a level
are spawned before those lower or right of them.)

Some sprite collision properties are incompatible with some clippings. For example sprites (The
ones in the Well of Wishes) cannot have clipping = 2 or you will get a 'fullcliptowall' error. This
happens when a sprite wants to do something to a tile because of its collision type, but the
clipping forbids it. If this happens, just change the collision type (Section 14)

Following is a list of sprites complete with their clipping, followed by a list of sprites and their
foreground behavior values.
