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, Slicestars will
give a 'fullcliptowall' error if they have clipping = 2 and hit a wall.

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