3D Viewer: Support Opacity as S value

Works in LW3, needed in LW4:

Note: Opacity scals between 0-100% opaque, based on the S value but S differs between various firmwares so kep in mind to read scale from settings

Might need a different approach that doesn't mess up the laser preview. Turn off gcode and documents but leave laser on for that example. Zoom in and out.

Aha! Thats what I was looking for! thick lines (0.1mm bam, 0.5mm stepover to show effect above) makes zoomed in view look better than lw3! Just need to document hiding gcode...

Also try with diagonal and the Sim slider :)

blown away! See thats why you need to post screen2gifs in development news again!

Been too busy coding. I think I did screen2gifs of laser preview a while back.

you did yes... will post some today (; keep on coding!
