; Draw a texture . . woo hoo!
; t0 - texture

; The texture coordinates need to be defined as follows:
; tc0 - texcoords

tex t0 ; shadow color
texkill t1 ; Clip
texkill t2
texkill t3 ; backface cull
; Darkening equation, compute a color = (shadow color * shadow alpha + 1- shadow alpha)
;sub r1, t0, v0.a ; r1 = shadow alpha
lrp r0.rgb, t0.a, v0, c0 + ; r0.rgb = (shadow color * shadow alpha + 1 - shadow alpha)
