Feature requests regarding painters.

* If a color is undefined (or set to "Nil"), it should be ignored instead of defaulting to black.
There are missile effects that are useful if only one of the colors are drawn instead of both. The default of black for an undefined color is not good enough because black will be drawn over space while the ship is close to a star (and anything else that is under the black effect). Note, color of "0x00, 0x00, 0x00" should still draw black. Just that color of "Nil" or no color should be completely transparent.

* Add a variant of the beam type "lightning" called "lightningBeam" or "lightningBolt".
All of the current lightning bolt effects are shaped like tear drops and do not look good as continuous beams like those fired by a lancer. I like to be able to create a weapon that shoots a long lightning beam, a bit like the lightning gun from the Quake series. The beam effect that is closest to what I want is "lightning" with no primaryColor defined. However, no primaryColor sets that part of the beam black, which causes that segment of the beam to flicker periodically, or appear black when space is not black. What I would like for this hypothetical "lightningBolt" effect is to draw only the secondaryColor part of the current "lightning" beam effect. Even this secondaryColor part of the "lightning" beam seems to consist of at least two jagged lines, and should support primaryColor and secondaryColor. In addition, this new beam's endpoints should be extended a few pixels longer than the current "lightning" beam.
