; Functions provided:

		[	:LNOT::DEF:sprite__dfn
		GBLL	sprite__dfn

; --- sprite_op ---
;
; On entry:	R0,R2-R7 ==  SpriteOp parameters (R1 set up here)
;
; On exit:	Registers and flags altered as for the SpriteOp
;
; Use:		Performs an OS_SpriteOp with the given arguments, using
;		the appication's Sprites resource as the sprite area.

		IMPORT	sprite_op

; --- sprite_getTable ---
;
; On entry:	R0 == pointer to a sprite
;		R1 == pointer to buffer for translate table
;
; On exit:	--
;
; Use:		Creates a colour translate table for the given sprite in
;		the specified buffer.
;
;		If you have a sprite name but no pointer, use OS_SpriteOp
;		24 to find the pointer -- this will make further sprite ops
;		on the sprite much quicker.

		IMPORT	sprite_getTable

; --- sprite_plot ---
;
; On entry:	R0 == pointer to a sprite
;		R1 == x coordinate to plot at
;		R2 == y coordinate to plot at
;		R3 == pointer to scale block, or 0 for 1:1
;
; On exit:	CS if the sprite was plotted OK, else CC
;
; Use:		Plots a sprite on the screen.  The scaling refers to the
;		sprite proper: /this/ routine takes care of odd pixel
;		sizes and things, so sprites don't appear squashed or
;		stretched unless you really want them to.
;
;		We return C clear on exit if we couldn't plot the sprite;
;		typically this would be if the sprite's mode is undefined.

		IMPORT	sprite_plot
