; Draw a texture . . woo hoo!
; t0 - texture
;
; The texture coordinates need to be defined as follows:
; tc0 - texcoords
; c1 - self-illum tint
; c2 - envmap tint
;------------------------------------------------------------------------------

tex t0
tex t1
tex t2
tex t3

mul		r0, t0, v0			; base times vertex color (with alpha)
mul		r1, t2, 1-t3.a		; envmap * envmapmask alpha
mad		r0.rgb, r1, c2, r0	; + envmap * envmapmask * envmaptint (color only)
mul		r0.rgb, t1, r0		; fold in lighting (color only)
mul_x2	r0.rgb, c0, r0		; * 2 * (overbrightFactor/2)
