TYPE: POP
TITLE: Sprite POP

The Sprite POP can be used to change a particle's sprite rendering properties
like texture coordinates, shop, rotation, and size.  The display options in
the viewport must be set to render particles as sprites in order for these
changes to have a visible impact.  The POP will add the attribute if it
doesn't exist already.

This POP modifies the following attributes: spriteuv, spriteshop, spriterot 
and spritescale.

Parameters:
    Activation          - Turns the POP on and off		/activate
    Source Group        - Subset of points to act on

    Texture Offset      - uv offset of lower-left corner	/textureoffset
    Texture Size        - texture size across sprite		/texturesize
    Sprite SHOP         - shop to use to shade the sprite       /spriteshoppath
    Resolve SHOP Path   - If set, the Sprite SHOP path is resolved
                          relative to this POP, and the spriteshop
                          attribute is set to the full path of the
                          shop.  If not set, no attempt is made to
                          find the shop, and the exact string entered
                          in the Sprite SHOP parameter is put into
                          the spriteshop attribute.  This will prevent
                          the sprites from rendering properly in the
                          POP Viewer.  The Geometry and Object Viewers
                          will still render the sprites properly if
                          the SHOP paths are specified relative to the
                          object that contains the POP Network.  This
                          option is most useful for creating custom
                          operators.
    Rotate              - the rotation about the view axis
                          in degrees				/rot
    Scale               - size of the sprite			/scale
