Fire uses fire_layer_0 and fire_layer_1

In 1.9 it seems that the Fire uses BOTH the fire_layer_0 and the fire_layer_1 texture, which is a HUGE disadvantage. i liked it, to keep my fire_layer_1 transparent (not sure if it was 0 or 1 ) so that way when I am burning my whole screen isn't red, but just slighty. Basically in 1.9 I can't do this.
