; Draw a texture . . woo hoo!
; t0 - texture
;
; The texture coordinates need to be defined as follows:
; tc0 - texcoords

def c2, 1.0f, 1.0f, 1.0f, 1.0f

tex t0
tex t1

; Blend between grey and lightmap color based on total alpha

mul_x2 r1.rgb, c0, t1		; Apply overbright to lightmap
+ mul_sat r1.a, t0, v0		; base times vertex alpha
lrp r0, r1.a, r1, c2		; interpolate between white + color
