Fix for issue #108
Better radius and spacing, see older revisions for billboarding
Upgraded JOGL to version 2.0.2
Switch back from spheres to screen aligned quads
Smoke and flame
Struggling back to smoke and flame I can be proud of.
Use a new smoke texture with much less transparenct and more HF noise.
Add an alpha function param to the trail function.
Lower quality texturing on the smoke. Smaller texture, linear filtering,
no anisotrophy.
Initial work with frag shader for smoke
Merge branch 'jogl-v2.0.2-RELEASE' into photobooth
Smoke is looking better, trouble with JOGL pre-multiplying alpha, I
think. Fixed by blasting color channel in the shader until I can figure
it out.
Flame looking good again
Add some higher frequency noise to the smoke normals
Scale flame to match motor. Kinda.
