Opacity for some 3D images #346
Description
A question for @APEXCalculus : there are some images (like this one) where we've set the opacity on the tangent plane (or some other overlapping surface) to 100%.
This is due to a limitation in WebGL: if you use a lower opacity, there's some bleeding that happens between the two surfaces.
If we build a PNG file instead, we can have lower opacity and avoid this issue.
So there is a tradeoff: we can have interactive 3D images, or we can have transparency, but we can't have both.
If you have to choose between the two, which do prefer to keep?
