This command is used to specify
the type of collision an image should perform.
useMask is a boolean value containing whether or not
the image should perform mask based collision. If this value
is false then it simply uses a rectangle to perform collision,
if it is true then it handles collision based on the images shape.
tolerance is used in conjunction with mask collision.
It is a value of how sensitive to collision that image is. This
is a value between 0 (least sensitive) and 255 (most sensitive).
image is the index into a bank of the image to alter
the collision information for
bank is an optional parameter specifying a bank to
get the image from. If this is not specified then the default
image bank is used.
