ElixirDoom.Gpu.Shimmer (elixir_doom v0.2.0)

Doom's shimmer (a spectre, a partly invisible player's weapon) as a graphics card material: the picture's shape filled with what is behind it, each row taken from one of Doom's 200 screen rows above or below, darkened as light table 6 darkens.

{material, live} = ElixirDoom.Gpu.Shimmer.material(live, target, picture, table)

table is the fixed light table in force, or nil; it keys the material with the picture's texture through that table, whose alpha cuts the shape.
