-Particle blend
---------------
-Blend function is defined by integer number.
-There is a huge number of acceptable blend modificators.
-Colour of a resulting pixel calculated using formulae:
-
- red = source_red * source_factor + destination_red * destination_factor
-
-and so on for every channel.
-
-Here is a some examples:
-
-Default value:
-
- material_type_param = 0,
-
-Use this value to disable blending. Texture will be applied to existing pixels
-using alpha channel of it. Its recomended to use 1-bit alpha
-in that case. This value will leave z-buffer writeable.
-
-Additive blend:
-
- material_type_param = 12641,
-
-Source = src_alpha, destination = one, alpha source is a texture and
-vertex_color, modulate_1x.
-Black color is completely transparent, white color is completely opaque.
-Alpha channel still used to calculate result color, but not nessesary.
-'destination = one' means that resulting color will be calculated using
-overwritten pixels values.
-For example with color of source (our texture) RGBA = (0,192,255,63)
-"blue-cyan", 1/4 opaque.
-and already rendered pixel color (40,192,0) "dark lime green" we will get color:
-
-R = source_red(0) * source_factor(src_alpha=63/255) +
- destination_red(40) * destination_factor(one) =
- 0 * 63/255 + 40 * 1 = 40
-
-G = 192 * 63/255 + 192 * 1 = 239
-B = 255 * 63/255 + 0 * 1 = 63
-
-Result: (40,239,63), "green" (a kind of).
-Note, if you made a texture with some kind of shape with colour 662211h
-it will appear dark red with a single particle, then yellow with a
-several of them and white if player looking thru a lot of them. With
-this you could made a nice-looking fire.
-
-Substractive blend:
-
- material_type_param = 12548,
-
-Source = zero, destination = src_color, alpha source is a texture and
-vertex_color, modulate_1x.
-Texture darkness act like an alpha channel.
-Black color is completely opaque, white color is completely transparent.
-'destination = src_color' means that destination in multiplied by
-a source values. 'source = zero' means that source values ignored
-(multiplied by 0).
-
-Invert blend:
-
- material_type_param = 12597,
-
-Source = one_minus_dst_color, destination = one_minus_src_alpha, alpha source
-is a texture and vertex_color, modulate_1x.
-Pixels invert color if source color value is big enough. If not, they just
-black.
-'destination = one_minus_src_alpha' means, that effect is masked by a
-source alpha channel.
-
-You can design and use your own blend using those enum values and function
-'minetest.pack_texture_blend_func'. Returned value of a function is
-your 'material_type_param'.
-
-A values in a brackets is a multiplicators of a red, green, blue
-and alpha channels respectively.
-
-* 'minetest.ebf': global table, containing blend factor enum values. Such as:
- * zero = 0 -- src & dest (0, 0, 0, 0)
- * one = 1 -- src & dest (1, 1, 1, 1)
- * dst_color = 2 -- src (destR, destG, destB, destA)
- * one_minus_dst_color = 3 -- src (1-destR, 1-destG, 1-destB, 1-destA)
- * src_color = 4 -- dest (srcR, srcG, srcB, srcA)
- * one_minus_src_color = 5 -- dest (1-srcR, 1-srcG, 1-srcB, 1-srcA)
- * src_alpha = 6 -- src & dest (srcA, srcA, srcA, srcA)
- * one_minus_src_alpha = 7 -- src & dest (1-srcA, 1-srcA, 1-srcA, 1-srcA)
- * dst_alpha = 8 -- src & dest (destA, destA, destA, destA)
- * one_minus_dst_alpha = 9 -- src & dest (1-destA, 1-destA, 1-destA, 1-destA)
- * src_alpha_saturate = 10 -- src (min(srcA, 1-destA), idem, ...)
-
-* 'minetest.emfn': global table, containing modulate enum values.
- * Multiply the components of the arguments, and shift the products to the
- * left by x bits for brightening. Contain:
- * modulate_1x = 1 -- no bit shift
- * modulate_2x = 2 -- 1 bits shift
- * modulate_4x = 4 -- 2 bits shift
-
-'modulate_4x' is quite useful when you want to make additive blend stronger
-with a lower amount of particles.
-
-* 'minetest.eas': global table, containing alpha source enum values. Such as:
- * none = 0 -- do not use alpha.
- * vertex_color = 1 -- use vertex color alpha.
- * texture = 2 -- use texture alpha.
-
-You can use both 'vertex_color' and 'texture' source by using value 3.
-
-* 'minetest.pack_texture_blend_func(srcFact, dstFact, modulate, alphaSource)': return integer
- * Pack texture blend funcion variable. Depending from that variable blend
- * function will be applied in time of a render poligons with selected material.
- * Therefore resulting pixel will be 'source * srcFact + destination * dstFact'
- * Use result of this function as 'material_type_param'.
