This does not fix the smokesim. It only port the drawing method. The Object mode engine is in charge of rendering the velocity debugging. Things left to do: - Flame rendering. - Color Ramp coloring of volume data. - View facing slicing (for now it's only doing sampling starting from the volume bounds which gives a squarish look) - Add option to enable dithering (currently on by default.
